Foglight 6.1.0 - Administration and Configuration Guide

Administering and Configuring Foglight Extending Your Monitoring Reach with Foglight Cartridges Administering Foglight Configure Rules and Metric Calculations to Discover Bottlenecks Customizing Your Foglight Environment with Tooling

Foglight Agent Manager Performance Overview

Explore the Foglight Agent Manager (FglAM) Overview view

The Overview view shows the numbers of remote hosts and Foglight agent instances that are connected to the Foglight Management Server. It also shows the maximal length of time spent by the Agent Manager (FglAM) on data polling.

Explore the Message Processing tab

The Message Processing tab shows tables for the number of pending messages and the number of incoming queue threads for a selected FglAM instance.

Explore the Clock Skew tab

The Clock Skew tab contains a graph that displays the upstream difference per second for a selected FglAM instance.

Explore the Bandwidth tab

The Bandwidth tab displays metrics for bandwidth usage samples taken at prescribed intervals per second for a selected FglAM instance, including the bytes in, bytes out, and real request time for a selected servlet. The bandwidth statistics reflect the bandwidth (bytes per second) used by the FglAM instance data over a specific time interval.

Explore the Misbehaving Clients tab

The Misbehaving Clients tab displays the disconnections per count for a selected FglAM instance.

Explore the XML Serialization tab

The XML Serialization tab shows tables of the serialization rate and time for the message serialization to and from XML for a selected FglAM instance.

The CPU tab displays the amount of time the CPU associated with a selected FglAM instance spends executing active processes and their number. For example, a sudden increase in CPU time may indicate that the user code is running inefficiently or a possible runaway process. Also, high CPU loads sometimes suggest that the host needs more CPU power to run efficiently.

The Memory Usage tab displays the amount of available memory and swap space for a selected FglAM instance. For example, a shortage of swap space often suggests a memory shortage, while a decline in the available memory may indicate a memory leaking process.

The CDT Submission tab displays information about the complexity of data that agents collect and submit for Canonical Data Transform (CDT) processing. Excessively large values or sudden increases in this data can result in performance problems.

The following metrics are displayed for each agent:

CDT Node Count: The number of internal data nodes produced by the CDT. Typically, there is one node for each topology object and its metrics, and one global (root) node in the tree.
CDT Value Count: The number of metrics and/or observations produced by the CDT.
Max Stack Depth: The depth of the data tree structure submitted by each agent instance. When a topology object in the data submission refers to another topology object, that increases the depth by one. When the second object refers to a third, the depth is increased again.
Node Count: The number of nodes in the submission. It is a measure of how large the data submission is.
Pre-processing time: The Agent Manager makes two passes over the data submitted by an agent. This is the time spent on the first pass, when the Agent Manager fills in references, validates the submission, calculates missing timestamps, and performs other pre-processing tasks.
Processing time: The length of time it takes the Agent Manager to transfer the data submission to the CDT processing engine of the Management Server.

Backing Up and Restoring Foglight

The following table shows the possible ways of backing up Foglight, some of which include the backup of the file system, and in some cases the system registry (on Windows). Each option shows a sequence of actions that can be performed to back up Foglight.

Issue a mysqldump command to export the MySQL database.

Alternatively, use the InnoDB HotBackup tool to back up the embedded MySQL database.
Issue a mysqldump command to export the MySQL database to a remote drive or a backup tape.
TIP: If you want to restore the database to a non-embedded PostgreSQL server, see the “Foglight Two Tier” section followed in this table.
Issue a mysqldump command to export the MySQL database to a remote drive or a backup tape.
Alternatively, use the InnoDB HotBackup tool to back up the embedded MySQL database.
Issue a mysqldump command to export the MySQL database.
Issue a pg_dump command to export the PostgreSQL database.
The default password is “foglight” that was set during the installation. The database information can be found in the server.database.* settings under <Foglight_home>/config/server.config.

a
Open a Windows® Explorer window, and right-click on My Computer.
b
Select Properties.
c
Click the Advanced tab and click Environment Variables.
d
Visually inspect the values associated with the PATH and LD_LIBRARY_PATH & ORACLE_HOME variables.
A dbdump file is created.
database_user is the name of the database user, as configured by the foglight.database.user parameter in <Foglight_home>/config/server.config.
database_port_number is the database port number, as configured by the foglight.database.port parameter in <Foglight_home>/config/server.config.
database_hostname_or_ip is the name of the computer on which the database is installed, or its IP address, as configured by the foglight.database.host parameter in <Foglight_home>/config/server.config.
database_name is the database name, as configured by the foglight.database.name parameter in <Foglight_home>/config/server.config.
--routines is a flag that ensures that all functions are included in the backup.
backupfile_name is the name of the backup SQL file.
3
After the backup SQL file is created, stop the MySQL database by issuing the shutdownDb.bat command from the <Foglight_home>/bin directory.
4
Verify that the database is down by verifying that the database process, mysqld.exe, is no longer running using the Task Manager.
Where Foglight_home contains the path to the Foglight installation directory. For example, its default location on Windows is C:\Quest\Foglight.
datadir="Foglight_home/mysql/data"
innodb_data_home_dir="Foglight_home/mysql/data"
innodb_data_file_path=ibdata1:10M:autoextend
innodb_log_group_home_dir="Foglight_home/mysql/data"
set-variable=innodb_log_files_in_group=2
set-variable=innodb_log_file_size=64
datadir="path_to_backup_data"
innodb_data_home_dir="path_to_backup_data"
innodb_data_file_path=ibdata1:10M:autoextend
innodb_log_group_home_dir="path_to_backup_data"
set-variable=innodb_log_files_in_group=2
set-variable=innodb_log_file_size=64
Foglight_home contains the path to the Foglight installation directory.
path_to_backup_data contains the path to the directory that is to contain the backup files, as defined in Step 1.
For example, C:\Quest\Foglight\backup\data (Windows).
When you are done, save the files in the config directory that you have created in Step 1.
NOTE: The above example illustrates the process of backing up a MySQL database on Windows, which uses the back slash character as a directory separator and the dir command to list files. On Unix platforms, use the forward slash to separate directories and the list -l command.
The backup directory contains one data file, ibdata1, and a log file, ibbackup_logfile. The backup process copies different database pages at different times. The log file, ibbackup_logfile, specifies the order in which the pages are backed up. Applying the log file to the backup data associates each database page with a sequence in the log file, and creates one or more log files for each data file, allowing you to successfully restore the database from the backup data when required.
C:\Quest\Foglight\mysql\bin>ibbackup --apply-log
NOTE: The example bellow illustrates the process of backing up a MySQL database on Windows, which uses the back slash character as a directory separator and the dir command to list files. On Unix platforms, use the forward slash to separate directories and the list -l command.
10/24/2008 10:55 AM 10,485,760 ibdata1
In addition to the files ibbackup_logfile and ibdata1 that were created at backup time (see Step 5), the backup directory now includes two additional log files, ib_logfile0 and ib_logfile1, which means that the logs have been applied successfully.

“Restoring” a physical backup means reconstructing it and making it available to users. This section outlines how to restore an old Foglight installation. The process is similar for Windows and Unix systems.

For more information about command-line options, see the Foglight Command-Line Reference Guide.

The previous Foglight installation is now restored.

2
Copy the backup data that was created with the InnoDB tool, including the data files and the log files, to the directory <Foglight_home>/mysql/data. The backup data and log files use the following naming convention:
ibdata<1-n>. The name of the first data file is ibdata1, of the second ibdata2, and so on. The number of data files depends on the size of the backed up database.
ib_logfile<0-n>. The name of the first log file is ib_logfile0, of the second ib_logfile1, and so on. The number of log files depends on the size of the backed up database and the size of the log file specified in the backup configuration file, backup.cnf.

In some cases it may be required to move the Foglight Management Server to different hardware. This may result in a change to the Management Server host name, IP address, or both, while the database may or may not move.

If the host name changes, you must obtain a new Foglight license.To receive a new license, send an email to license@quest.com with your contact and site ID information, along with an explanation of why you need a license. Changing only the IP address, while the host name remains the same, does not require a license update.

If the host name changes, you must also update the CATALYST_URL registry variable. This registry variable contains the Management Server host name and port, which are used to build the alarm URLs sent in email message alerts. For more information about email settings, see Explore the Mail (Global Settings) view.

This sectiontopic describes the process of moving the Foglight Management Server to a different computer.

If the database is still running, use the shutdownDB command to shut down the database. For more information about this command, see the Command-Line Reference Guide.

Manage Rules

This dashboard is a starting point for viewing and customizing Foglight rules. It displays a list of all multiple-severity that exist in your environment, including the rules that come with the Management Server and any installed cartridges.

By default, the following columns are displayed:

Rule state: Indicates if the rule is enabled or disabled . You can sort the list of rules by state, by clicking the State icon.
Rule: Contains the rule name.
Copy: Creates a copy of the selected rule.
Disable (enabled rules only): Disables an enabled rule.
Enable (disabled rules only): Enables a disabled rule.
View and edit: Starts the workflow for viewing and editing rule details.
Other: Contains the value of any registry variables referenced by rule severity variables.
Alarms: Contains the number of alarms (multiple-severity rules only) generated by the rule. Clicking that column shows a list of alarms indicating for each alarm its severity, when the alarm was generated, and the alarm message.
Description: Contains the rule description.

The above columns appear by default. Click the Customizer to select the following columns for display:

Rulettes: The number of scoped objects to which the rule is bound. A rulette is a rule instance that represents the state of the monitoring object to which the rule condition applies. Clicking this column shows a list of all scoped objects.
Last Reset: The date and time of the most recent reset of the object’s state.
Triggers: The total number of times that the rule conditions evaluated the object instance.
Fired: The total number of times that the rule changed the state.
Hit: The total number of times that the rule conditions evaluated to True.
Miss: The total number of times that the rule conditions evaluated to False.
Last Fired: The most recent date and time when the rule changed the state.
Last Miss: The most recent date and time when a rule condition evaluated to False.
Cartridge: The name of the cartridge in which the rule is defined, including the cartridges included with the server, and any installed cartridges. This column is empty for rules that you create.
Cartridge Version: The version of the cartridge in which the rule is defined, including cartridges included with the server, and any installed cartridges. This column is empty for those rules that you create.
Last Modified Date: The date on which the rule was last modified.
Scope: This can give you a better idea on the effect that the rule has on your monitored system. The scope identifies one or more topology objects that the rule evaluates. If the scope is not defined, the rule runs against the entire data set, which can have a negative effect on overall performance. A rule can be scoped to a topology type and can optionally be scoped to specific topology objects of that type. For more information, see Rule scope.
Object Name: The name of the scoped object instance.
Unique ID: The ID of the scoped object instance.
Aggregate State: The state of the scoped object instance, representing the highest severity alarm state generated against this instance: Normal, Warning, Critical, or Fatal.
Type Name: The name of the topology type that the object is an instance of.

Use the Enable and Disable buttons in the top-left to enable or disable selected rules.

To filter the list of rules by cartridge, click Cartridge in the top left and select a cartridge from the list that appears.

To access the Manage Rules dashboard, click Old Manage Rules. Use this dashboard to access an extended set of rule management tasks that cannot be initiated from the Rule Management dashboard, such as editing rule permissions, and suspending or resuming rule actions.

Foglight has a way to control access to different entities, including rules. While it is possible to use permissions to control access to rules, this feature is deprecated and should not be used.

Copying a rule is useful in situations when you need to quickly create a modified version of an existing rule. If you need to edit an existing rule, it is considered good practice to copy the rule, disable the original rule, then make your modifications. This makes it possible to refer back to the original rule definition, or re-enable it after disabling the modified version, if necessary.

Rules can be copied using either the Rule Management dashboard, or the Manage Rules dashboard. Rules can be deleted using the Manage Rules dashboard.

1
On the navigation panel, under Dashboards, choose Administration > Rules & Notifications > Rules.
3
In the Copy dialog box, specify the new rule name (optional, a default name already appears), indicate if you want to disable the original rule (default setting) or not, and indicate if you want to enable the new rule (default setting) or not.

The Rule Summary pane includes the following information:

1
On the navigation panel, under Dashboards, choose Administration > Rules & Notifications > Rules.
NOTE: Some browser versions do not support the nested rendering of the Edit Rule page that you are about to access. If you are using those browser versions, click Launch in the display area, as prompted, to open the Edit Rule page in a new window or tab.
3
On the Manage Rules dashboard that appears, click the Rule Name column of the row containing the rule whose summary you want to view.
The Edit Rule view appears in the display area.
4
Open the Rule Summary pane by clicking Roll Down () on the Rule Summary bar.
NOTE: The appearance of the Rule Summary pane depends on the rule type, its severity levels, and other settings. In the above illustration, the rule whose settings appear in the Rule Summary pane is active.
The Rule Summary pane includes links to other areas in the Edit Rule view and Manage Rules dashboard that allow you to quickly edit the rule settings.
For example, move the mouse pointer over Rule Triggering in the Rule Summary pane. A tool tip appears, with the text: Edit Trigger Type.

The Rule Diagnostics dashboard lists all rules that exist in your environment, including the rules available with the server and any installed cartridges. Use this dashboard to better understand how the existing rules are operating and to debug any rule-related problems.

For each rule, the Rule Diagnostics dashboard shows the following information:

Name: The rule name.
Scope: The rule scope. This can give you a better idea on the effect the rule has on your monitored system. The scope identifies one or more topology objects that the rule evaluates. If the scope is not defined, the rule runs against the entire data set which can have a negative effect on overall performance. A rule can be scoped to a topology type and can optionally be scoped to specific topology objects of that type. For more information, see Rule scope.
Trigger: The trigger type. This value affects the frequency at which the rule conditions are evaluated. The rule trigger gives you a general idea of the rule activity and the alarms it generates. For example, a default data-driven trigger causes the rule conditions to be evaluated every time the data associated with the rule is collected and higher data sampling frequencies result in a higher number of alarms being generated. For more information, see Rule triggers.
Rulettes: The number of scoped objects to which the rule is bound. A rulette is a rule instance that represents the state of the monitoring object to which the rule condition applies.
Cartridge: The name of the cartridge in which the rule is defined, including the cartridges included with the server, and any installed cartridges. This column is empty for those rules that you create.
Cartridge Version: The version of the cartridge in which the rule is defined, including cartridges included with the server, and any installed cartridges. This column is empty for those rules that you create.
Enabled: Indicates if a rule is enabled or disabled. When a rule is disabled, its conditions are not being evaluated which prevents the rule alarms from being generated. For example, if Foglight is collecting any data that, under normal circumstances, result in alarm generation. Failing to generate alarms can be an indication that the rule is disabled. Rules are often brought offline during system maintenance periods.

From here, you can drill down to a rule to see additional diagnostics about that rule. To do that, click the row containing the specific rule and, in the dwell that appears, under Go to, click Diagnostic Details.

For more information about the Diagnostic Details view that appears, see View diagnostic details for a rule.

The Diagnostic Details view contains detailed run-time information about a selected rule. Use this view to determine which objects are evaluated by the rule and as a debugging tool to help you understand any rule-related problems. Drill down to this view from the Rule Diagnostics dashboard.

This composite view contains the following embedded views:

Shows rule definitions.

Name. The rule name.
Type. A rule type can be either simple or multiple-severity. A simple rule has a single condition, and when that condition evaluates to True, the rule enters the Fire state. Multiple-severity rules are more complex in that they can have multiple conditions and multiple the severity levels, including Warning, Critical, and Fatal. For more information, see Rule types.
Rule Scope. The rule scope. This can give you a better idea on the effect the rule has on your monitored system. The scope identifies one or more topology objects that the rule evaluates. If the scope is not defined, the rule runs against the entire data set which can have a negative effect on overall performance. A rule can be scoped to a topology type and can optionally be scoped to specific topology objects of that type. For more information, see Rule scope.
Cartridge. The name of the cartridge in which the rule is defined, including the cartridges included with the server, and any installed cartridges. This column is empty for those rules that you create.
Cartridge Version. The version of the cartridge in which the rule is defined, including cartridges included with the server, and any installed cartridges. This column is empty for those rules that you create.
Comments/Description. Comments or notes associated with the rule.
Alarm Description. Description of the alarm message.
Enabled. Indicates if a rule is enabled or disabled. When a rule is disabled, its conditions are not being evaluated which prevents the rule alarms from being generated. For example, if Foglight is collecting any data that, under normal circumstances, result in alarm generation. Failing to generate alarms can be an indication that the rule is disabled. Rules are often brought offline during system maintenance periods.
Blackout. Indicates if there are any blackouts in place that affect the rule’s actions.
Alarms. Indicates if the rule alarms are enabled or disabled. When rule alarms are suspended, the rule continues to evaluate the collected data but does not generate alarms when its conditions are met. For more information, see Suspending or resuming rule alarms.
Actions. Indicates if the rule actions are enabled or disabled. When rule actions are suspended, the rule continues to evaluate the collected data but does not generate actions when its conditions are met. For more information, see Suspending or resuming rule actions.
Trigger Type. The trigger type. This value affects the frequency at which the rule conditions are evaluated. The rule trigger gives you a general idea of the rule activity and the alarms it generates. For example, a default data-driven trigger causes the rule conditions to be evaluated every time the data associated with the rule is collected and higher data sampling frequencies result in a higher number of alarms being generated. For more information, see Rule triggers.

Lists one or more object instances to which the rule is bound, and shows information about the rule activity, as it relates to each object instance. Selecting a table row shows additional statistics about the rule activity in the Rulette Details View.

Long Name. The name of the object instance evaluated by the rule and its data type.
Last Reset. The date and time of the most recent reset of the object’s state.
Triggers. The total number of times the rule conditions evaluated the object instance.
Fired. The total number of times the rule changed the state.
Hit. The total number of times the rule conditions evaluated to True.
Miss. The total number of times the rule conditions evaluated to False.
Last Fired. The most recent date and time the rule changed the state.
Last Hit. The most recent date and time a rule condition evaluated to True.
Last Miss. The most recent date and time a rule condition evaluated to False.

For the object instance selected in Rulettes for Rule View, this view shows detailed statistics about the rule execution, broken into severity levels.

Severity. The severity level associated with the condition that was evaluated against the selected object instance.
Fire. The total number of times the rule entered the severity level.
Hit. The total number of times the condition associated with this severity level evaluated to True.
Miss. The total number of times the condition associated with this severity level evaluated to False, or were not evaluated. If a condition is not defined for a severity level, it is not evaluated.
Last State. The result of the most recent severity-specific condition evaluation. It can have one of the following values:
Hit: The condition evaluated to True.
Miss: The condition evaluated to False.
Not evaluated: The condition was not evaluated. If a condition is not defined for a severity level, it is not evaluated.
Name. The name of the metric evaluated.
Object Name. The name of the object instance to which the rule is bound.
Object Type. The type of the object instance to which the rule is bound.
Drill down on an entry in the Observations table. Displays a dwell that shows the health of the object instance the metric is associated with, identifies any agents or hosts related to this instance, and lists links to views that reference the object instance, including the Property Viewer and Metric Analyzer. From here, clicking a link under Related drills down to the selected view.

Foglight uses flexible rules to apply your business logic to complex, interrelated data from multiple sources within your distributed system. A rule is a piece of business logic that links a condition with a result. It includes a scope and one or more conditional expressions, alarm messages, and actions.

A typical installation can include a large number of rules. You can create and manage multiple-severity rules using the Rule Management dashboard. The Rule Management dashboard lists the rules that exist in your environment and allows you to manage them.

Use this dashboard to drilldown on a rule and to view and edit its definitions. When you edit existing rules allows you can customize how Foglight notifies you of the status of desired metrics and specify what actions should be performed when their status changes.

Foglight uses flexible rules to apply your business logic to complex, interrelated data from multiple sources within your distributed system. A rule is a piece of business logic that links a condition with a result. It includes a scope and one or more conditional expressions, alarm messages, and actions.

Many rules come included with Foglight and installed cartridges, including Agent Health State, BSM All Events, Catalyst Data Service Discarding Data, and many others. If the existing rules do not meet your needs, you can create a new one and add it to the rule collection.

By creating new rules or editing existing ones, you affect how Foglight notifies you of the status of desired metrics and specify what actions should be performed when their status changes.

1
Open the Create Rule dashboard. On the navigation panel, under Dashboards, choose Administration > Rules & Notifications > Create Rule.

Rule definitions specify the time at which they are evaluated, their complexity, and in some cases, the topology objects they evaluate. Rule definitions can be divided into the following categories:

There are two types of rules in Foglight. Those types are Simple rules and Multiple-severity rules.

A simple rule has a single condition, and can be in one of three states:

If its condition is met, the state of the rule is set to Fire and any actions that are associated with this state are performed. If the condition is not met, the rule remains in the Normal state. If the rule’s condition cannot be evaluated because data is missing or unavailable, the state of the rule is set to Undefined and any actions that are associated with this state are performed.

The condition for a simple rule is regularly evaluated against monitoring data. Therefore, the state of the rule can change if the data changes. For example, if the collected data matches a simple rule’s condition, the rule enters the Fire state. If the next set does not match the condition, the rule exits the Fire state and enters the Normal state. You can configure a simple rule to perform one or more actions upon entering and/or exiting each state.

A multiple-severity rule is a more complex type of rule that can have up to five severity levels:

When you create a multiple-severity rule, you must specify a condition for at least one severity level (Fatal, Critical, or Warning).

As with simple rules, the conditions for a multiple-severity rule are regularly evaluated against monitoring data. All conditions in a rule are evaluated; the severity state is set to the highest level for which the condition evaluates to True. If none of the conditions are met, the severity state is set to Normal. If a condition cannot be evaluated because data is missing or unavailable, the state is set to Undefined.

An alarm is generated each time a multiple-severity rule enters a new state. In addition, you can configure a multiple-severity rule to perform one or more actions upon entering and/or exiting each state.

Generated alarms can be viewed in Foglight dashboards that exist outside of the Administration module, such as the Alarms or Agents dashboards. In addition to viewing alarm details, these dashboards allow you to drill down to alarm details, and to clear and acknowledge alarms.

The alarm list can show multiple alarms that are generated by the same rule. This is because rule conditions are evaluated repeatedly, after each data sampling interval. If rule conditions are met in subsequent sampling intervals, Foglight generates an alarm instance for each positive condition evaluation. These alarms can be of the same or different severity, depending on the value of the collected data. For example, a rule can produce multiple Warning alarms, or alarms whose severity ranges from Warning through Critical to Fatal.

Each alarm can be acknowledged or cleared. Acknowledging an alarm indicates that the Foglight operator is aware of the alarm. You can acknowledge a single alarm instance (by clicking Acknowledge in the alarm drill-down dialog box), or all consecutive alarms generated by the same rule (by clicking Acknowledge Until Normal).

Clearing an alarm indicates that the alarm is examined by the Foglight operator and that it is safe to remove it from the list. Along with cleared alarms, any acknowledged alarms can be removed from the list if required using the alarm filter.

For more information about working with alarms, see the Foglight User Guide.

Rule triggers determine the time at which its conditions are evaluated against the collected data. A rule can have one of the following triggers:

Unlike simple rules, that fire without raising any alarms, multiple-severity rules can generate alarms when their conditions are met. These alarms appear in many different dashboard. You can also create your own dashboards that display alarms. In order for alarms to work correctly in dashboards, they must be generated by multiple-severity, data-driven rules. Alarms generated by multiple-severity, time- or event- driven rules do not have the same functionality in dashboards as multiple-severity, data-driven rules.

A time-driven trigger causes one or more of a rule’s conditions to be evaluated once per pre-defined interval. By default, time-driven rules are only evaluated if data for the evaluation of the condition is available, but you can override this behavior, if required.

If a rule has a data-driven trigger, one or more if its conditions will be evaluated every time that new data associated with one or more topology types or objects to which the rule applies is sent to the Foglight Management Server. This option is selected as the default trigger.

An event-driven trigger causes one or more of a rule’s conditions to be evaluated as a response to a certain event. There are four types of events that can act as rule triggers:

AgentManagementSystemEvent: Foglight generates these types of events when an agent instance enters a certain state. Examples of agent states include New Instance, Registered, Unregistered, Activated, Deactivating, Data Collection Starting, Data Collection Stopping, and Obsoleted. These types of system events allow you to monitor the agents’ state and evaluate it in rule conditions.
AlarmSystemEvent. Multiple-severity rules generate system events when a rule severity level is reached, such as the Warning, Critical, or Fatal state. Alarm-based system events allow you to trigger alarm-related rules. This type of events can be useful, for example, when forwarding alarms to an external system or when sending notifications.
IncidentSystemEvent. Foglight creates an incident system event when an incident is created or modified. Incidents are used to group alarms based on a common parameter, and can result in ticket requests generated in an external system. The types of incident modifications you can evaluate in rule conditions include Create, Close, Acknowledge, Modify, and Delete.
ReportGeneratedEvent. Report generation creates events. You can monitor those events as required and use them to trigger report-related events.The type of report properties that you can evaluate in rule conditions include name, reportId, user, templateName, and many others.

A schedule-driven trigger causes one or more of a rule’s conditions to be evaluated during which a selected schedule is in effect. By default, schedule-driven rules are only evaluated if the data for the evaluation of the rule condition is available, but you can override this behavior, if required.

The scope of a rule defines the set of topology objects against which it runs. A rule can be scoped to a topology type and can optionally be scoped to specific topology objects of that type. If a rule is not scoped to specific objects, it applies to all instances of that type. The scope object is the object on which alarms will appear in the Foglight interface. The rule scope is specified using the query language. For more information, see Using the Query Language.

A rule can apply to a topology type or to one or more objects of that type. You can change the scope of a rule (the topology type or one or more specific topology objects to which it applies) after its creation.

Use the Rule Definition tab to edit rule definitions. This tab allows you configure basic settings, such as the rule name, description, and alarm message. It also contains the settings for specifying the rule complexity, its trigger, and scope.

Rule expressions can reference different types of variables:

Foglight registry variables can be used in rule conditions, derived metric expressions, and rule-specific actions. A registry variable can have a global value that is available to all topology types and objects. It can also have one or more values associated with specific topology types or objects, or calendar dates. For more information, see Working with Foglight Registry Variables.

Foglight includes trigger-specific rule variables that can be used in conditional expressions of rules with certain trigger types. Each variable contains the information relative to the rule in which it is used. For example, if you create Rule A and use the rule-level variable foglight_rule_name as a parameter in an action that you add to Rule A, that parameter uses the actual rule name, Rule A.

Rules in Foglight can be triggered by data, time, or events. Different trigger types, such as time, data, and event triggers, have different rule-level variables available to them. For example, in an event-driven rule you can reference the properties of the system alarm event that triggers the rule directly.

Most of the rule variable are available in all contexts within a rule. However, foglight_rule_alarm_link, foglight_monitored_host_name, foglight_monitoring_agent_name and foglight_severity_message are not available in rule condition scripts. Also, foglight_severity_message is also not available at rule level. It is available only as severity level.

Unlike severity-level variables, that can only be referenced in the expression associated with the severity level in which the variables are defined, rule-level variables can be referenced in any severity level.

There are two types of rule-level and severity-level variables:

Expressions. An expression is used to retrieve data. It can contain a registry variable or a function.
Messages. A message is typically a text string that can include other severity-level variables, displaying dynamically-supplied data about your monitored system.

Message

Rule-level variables can be referenced in conditional expressions in multiple severities. When your threshold requirements change, you can create new or edit the existing rule-level variables. Editing an existing rule-level variable affects the outcome of any rule conditions or alarm messages that reference that variable. If you plan to write or edit a conditional expression or an alarm message that includes one or more rule-level variables, ensure that those variables exist prior to writing the expression.

Click Add.
The Severity Level Variables pane refreshes, showing the newly-added variable.

A condition is the part of a rule that is evaluated against monitoring data. When it evaluates to True, the rule is said to fire, causing any actions that are associated with the rule or severity level to be performed.

When you create a simple rule, you specify a single condition for it. You can edit this condition after you create the rule. When you create a multiple-severity rule, you must specify a condition for one or more of its severity levels, Fatal, Critical, and Warning, along with an alarm message that is associated with each condition.

A conditional expression can be either true or false. Conditional expressions can reference registry, Groovy functions, and metrics associated with the one or more topology types or their topology objects to which the rule is scoped.

Additionally, conditional expressions can reference properties of topology objects that are related (within the hierarchy of the topology model) to one or more topology objects to which the rule is scoped. For example, the condition for a simple rule that is associated with a specific JVM can reference properties of the server on which the JVM is running (such as the server name), or properties of the cluster to which the server belongs.

Furthermore, event-driven rules can retrieve data generated by report- and alarm-related events.

Expressions can be simple—for example, an expression can consist only of a metric name—but they can also be defined using very complex syntax.

Conditional expressions make use of the query language. For more information, see Using the Query Language.

Foglight generates an alarm message when the conditional expression associated with a multiple-severity rule evaluates to True. An alarm message is typically a text string that can include other severity-level variables, displaying dynamically-supplied data about your monitored system.

Simple rules do not generate alarms. They fire when the condition for their Fire state is met. Multiple-severity rules generate alarms each time they enter a severity state.

Expressions and messages can be set with one of two distinct scopes: Rule-scoped expressions and messages and Severity-scoped expressions and messages.

They can be referenced by the actions set for the Fire and Undefined states of a simple rule and for all severity levels (Fatal, Critical, Warning, Normal, and Undefined) in a multiple-severity rule.

They can only be referenced by the actions set for the specific rule level at which the message is defined. For example, if an expression is defined for the Fatal level of a multiple-severity rule, it can only be referenced by the actions that are set for that severity level.

A conditional expression is the part of a rule that is evaluated against monitoring data. When it evaluates to True, the rule is said to fire, causing any actions that are associated with the rule or severity level to be performed. A conditional expression can reference variables, topology object metrics, and Groovy functions. Use the Condition tab to specify a conditional expression.

1
On the Conditions and Actions tab (simple rules) or Conditions, Alarms & Actions tab (multiple-severity rules), open the Conditions tab.
In the Condition tab, use the Condition area to write the conditional expression.
You can type the condition directly into the Condition box, or use the operator controls and the Condition Editor to add logical operators, registry variables, metrics, or Groovy functions.
IMPORTANT: Conditional expressions that reference metric properties using the syntax scope.get("aMetric") or metrics using the service layer (for example, server["DataService"].retrieveLatestValue(…)) prevent data-driven rules from firing. Similarly, failing to include a metric reference prevents data-driven rules from triggering. To reference a metric directly use the "#aMetric#" syntax.

println @event.dump();

@event.get("report/name") == "MyReport";

println @event.dump()

@event.get("report/name") == "MyReport";

println @event.dump();

println @event.dump()

3
Multiple-severity rules. Activate the condition by selecting Activate.
You must activate the condition for a severity level in a multiple-severity rule before you can save it. If the Activate check box is cleared when you click Save, the condition that you specified will be discarded, as will any expressions or actions that you set in the sub-tabs of the tab for that severity level.
IMPORTANT: Do not clear the Activate check box if you want to temporarily disable a rule. To temporarily deactivate the alarms and actions for an entire rule, follow the instructions in Suspending or resuming rule alarms. You can also configure the behavior of the alarms and actions for the rule. See Configure alarm and action behaviorfor more information.
4
Multiple-severity rules. Define the alarm message associated with the newly-defined condition.
In the Alarm box, type the alarm message.
5
Multiple-severity rules (Optional). To reference a rule-level variable or a system variable in the alarm message, in the Alarm Message box, click the location in which you want to add the variable, and then click the Alarm Message Editor button () above the Alarm Message box.
To add a rule-level variable, in the Alarm Message Editor dialog box, on the Rule Variables tab, select the rule-level variable and click Insert.
To add a system variable, on the System Variables tab, select the system variable and click Insert.
6
Save the newly-defined rule condition by clicking the Save button above the Condition tab.

When you write conditions for event-driven rules, in addition to variables, topology object metrics, and Groovy functions, you can use events and their properties to trigger rule actions.

Event-driven rules allow you to monitor the events generated every time a pre-defined event occurs. There are several types of events that can act as rule triggers: AlarmSystemEvent, DatabaseMaintenanceEvent, IncidentSystemEvent, and ReportGeneratedEvent.

Multiple-severity rules generate system events when a rule severity level is reached. Foglight creates an AlarmSystemEvent object instance for each alarm system event. The types of rule severity include Undefined, Normal, Warning, Critical, or Fatal state. The change property of an AlarmSystemEvent object instance indicates the rule severity. Alarm-based system events allow you to trigger alarm-related rules. This can be done by evaluating the values of AlarmSystemEvent properties in rule conditions.

Boolean

Determines if the event is acknowledged. It can be set to True or False.

Boolean

Determines if the event is cleared. It can be set to True or False.

Boolean

Indicates if the alarm is transitioning from the Warning, Critical, or Fatal state to Warning, Critical, or Fatal (as applicable). For new and clearing alarms, this value is always False. Foglight creates events for newly-created alarms, cleared alarms, or existing alarms transitioning to a new state, as follows:

Clearing alarms generate a single Clear event with isTransition set to False.

New alarms generate a single Fire event with isTransition also set to False.

Existing alarms transitioning from the Warning, Critical, or Fatal state to Warning, Critical, or Fatal (as applicable) generate two events: a Clear event for the old severity, and a Fire event for the new severity. The isTransition flag in both events is set to True.

External systems can make use of this behavior when evaluating events, to distinguish between clearing and non-clearing alarms.

Integer

Indicates the target the alarm is transitioning to. For clearing alarms, the next severity level is always 0 (Normal). Foglight creates events for newly-created alarms, cleared alarms, or existing alarms transitioning to a new state, as follows:

Clearing alarms generate a single Clear event with the next severity level of 0 (Normal).

New alarms generate a single Fire event with the next severity level of 2 (Warning), 3 (Critical), or 4 (Fatal).

Existing alarms transitioning from the Warning, Critical, or Fatal state to Warning, Critical, or Fatal generate two events: a Clear event for the old severity, and a Fire event for the new severity. The next severity level in both events is set to the target severity (Warning, Critical, or Fatal).

External systems can make use of this behavior when evaluating Clear events, to distinguish between clearing and non-clearing alarms.

String

Contains the alarm message.

Integer

Indicates the previous severityLevel the alarm is transitioning from. For new alarms, the previous severity level is always 0 (Normal). Foglight creates events for newly-created alarms, cleared alarms, or existing alarms transitioning to a new state, as follows:

Clearing alarms generate a single Clear event with the previous severity level of 2 (Warning), 3 (Critical), or 4 (Fatal).

New alarms generate a single Fire event the previous severity level of 0 (Normal).

Existing alarms transitioning from the Warning, Critical, or Fatal state to Warning, Critical, or Fatal (as applicable) generate two events: a Clear event for the old severity, and a Fire event for the new severity. The previous severity level in both events is set to the original severity (Warning, Critical, or Fatal).

External systems can make use of this behavior when evaluating Fire events, to distinguish between clearing and non-clearing alarms.

Foglight creates a DatabaseMaintenanceEvent as it performs maintenance operations during the nightly maintenance window. An event will be sent before each operation is run, and after it ends. The operationName property in the event specifies the operation that is being performed. The server also sends a started event for the "DatabaseMaintenance" operation before it runs the individual maintenance operations, and sends a ended event for "DatabaseMaintenance" operation after all the individual operations have been run.

Table 11. The DatabaseMaintenanceEvent object properties, their data types, and descriptions.

Foglight creates an incident system event when an incident is created or modified. Incidents are used to group alarms based on a common parameter, and can result in ticket requests generated on an external system. For each incident, Foglight creates an IncidentSystemEvent object instance. The types of incident modifications include Create, Close, Acknowledge, Modify, and Delete. The type of incident modification is indicated in the IncidentSystemEvent object’s change property. Incident-based system events allow you to trigger incident-related rules. This can be done by evaluating the values of IncidentSystemEvent properties in rule conditions.

A conditional expression is the part of a rule that is evaluated against monitoring data. When it evaluates to True, the rule is said to fire, causing any actions that are associated with the rule or severity level to be performed. In addition to variables, topology object metrics, and Groovy functions, a conditional expression associated with an event-driven rule can also reference the properties of the event that acts as the rule trigger. For example, you can write a condition for an event-driven rule that fires when Foglight generates a report.

1
On the Conditions and Actions tab (simple rules) or Conditions, Alarms & Actions tab (multiple-severity rules), open the Conditions tab.
In the Condition tab, use the Condition area to write the conditional expression. using the following syntax:
some_value.equals(@event.get("[object/]property");
report indicates that you want to use the ReportGeneratedEvent in the conditional expression.
object is the name of the event's property object whose property value you want to retrieve.
property is the name of the event property that you want to use in the comparison.
some_value contains the value that is to be compared with the specified property value.
@event.get("report/name") == "System Resources";
byte[] pdf_object =
server.get("ReportingService").getReportData(@event.get
Where pdf_object is the name of the report file that you want to retrieve.
3
Multiple-severity rules. Activate the condition by selecting the Activate check box.
You must activate the condition for a severity level in a multiple-severity rule before you can save it. If the Activate check box is cleared when you click Save, the condition that you specified is discarded, as are any severity-specific expressions or actions.
IMPORTANT: Do not clear the Activate check box if you want to temporarily disable a multiple-severity rule. To temporarily deactivate the alarms and actions for an entire rule, follow the instructions in Suspending or resuming rule alarms. You can also configure the behavior of the alarms and actions for the rule. See Configure alarm and action behavior for more information.
4
Multiple-severity rules. Define the alarm message associated with the newly-defined condition.
In the Alarm box, type the alarm message.
5
Multiple-severity rules (Optional). To reference a rule-level variable or a system variable in the alarm message, in the Alarm Message box, click the location to which you want to add the variable, and then click the Alarm Message Editor button () above the Alarm Message box.
To add a rule-level variable, in the Alarm Message Editor dialog box, on the Rule Variables tab, select the rule-level variable and click Insert.
The Rule Variables tab lists all of the rule-level variables, including expressions and messages.
To add a system variable, on the System Variables tab, select the system variable and click Insert.
6
Save the newly-defined rule condition by clicking the Save button above the Condition tab.

In some cases you may need to copy the conditions from an existing severity level. A condition is comprised of a conditional expression and an alarm message, both of which can be copied.

Copying a condition can be useful in situations when the conditional expressions of different severities are similar, so instead of writing and validating them for each severity level you can copy an existing expression and modify it to suit your needs.

While you are editing the rule, any unsaved changes to the conditional expressions or alarm messages that you want to copy will be carried over to the destination condition. For example, if you edit a conditional expression for the rule’s Warning severity without saving it, and then proceed to copy that condition in the Critical pane, any unsaved edits of the Warning condition will be carried over to the Critical condition.

Copying a conditional expression from one severity to another without modifying it results in multiple conditions with the same expression. While this type of rule configuration is allowed, a confirmation message appears to make you aware of that. When such a condition is met, it triggers the higher severity. For example, if both Warning and Critical conditions have the same expressions, when that condition is met, the rule enters the Critical severity. An exception to this case is when the expressions resolve the same condition using a slightly different combination of characters. For example, abc>1, abc >1, and abc > 1 are considered different expressions, and as such are evaluated separately.

1
Open the Conditions, Alarms & Actions tab.
2
On the Conditions, Alarms & Actions tab, open the Conditions tab.
a
Click the Copy condition/alarm button above the Condition tab.

An action is a particular operation that is performed when a rule enters or exits a state when its condition is met. Simple and multiple-severity rules can be associated with multiple actions. Additionally, each severity level in a multiple-severity rule can have one or more actions. Actions can be added to a rule after it is created.

For example, you can associate an email action with a rule condition. When the rule condition evaluates to True, Foglight sends an email to the selected recipient, with the alarm message in the email body.

There are two types of actions in Foglight:

Entering. It causes the action to be performed when a simple rule or a severity level in a multiple-severity rule enters the state in which the condition for that rule or severity level is met.
It is a best practice that Entering actions be used by default.
Exiting. It causes the action to be performed when a simple rule or a severity level in a multiple-severity rule exits the state in which the condition for that rule or severity level is met.
Use of the Exiting action should be restricted to cases where an action specific to the state is needed. For example, if an Entering action starts a script, then the Exiting action can be used to stop the script.

The actions available in Foglight are as follows:

BSM actions. Business Service Management (BSM) actions send alarm data to external systems such as Tivoli.
SNMP trap actions. They cause alarms to be forwarded as Simple Network Management Protocol (SNMP) traps to a management system that supports SNMP (such as Tivoli® NetView®, Micromuse NetCool® or HP® Vantage Point®) when the rule fires. Various parameters can be set for sending the SNMP trap, including the community, the host and port for the monitoring service.
Email actions. They cause email messages to be sent to a specified recipient when the rule fires. For more information about viewing the settings related to email actions and configuring email actions in Foglight, see Configuring email notifications
Command actions. They cause an external action to be executed on the computer on which the Foglight Management Server is installed. For example, a command action can run an executable that starts a service. Various parameters can be set for this action. The mandatory parameter is COMMAND_LINE which contains the name of the executable, along with one or more arguments. Optionally, you can also set OS environment variables (separated by exclamation marks).
Remote command actions. They cause an external action to be executed on a monitored host. Various parameters can be set for this action including the mandatory parameter COMMAND_LINE.
Script actions. They cause an arbitrary script, deployed inside the server (such as a Groovy script), that runs when the rule fires. This is to be used for any integration not available through built-in actions. Various parameters can be set for this action, such as script name (mandatory), scoping topology ID, scripting object ID, and arguments (up to ten) associated with the script. The number and order of arguments (0-9) specified as action parameters must match the script requirements. There is currently no validation facility for script actions.
1
In the Conditions and Actions tab (simple rules) or Conditions, Alarms & Actions tab (multiple-severity rules), open the Action tab.
Select one of the following Action Type options: Entering or Exiting.
Click Action and select an action from the list that appears. There are several actions to choose from: BSMAction, CommandAction, EmailAction, RemoteCommandAction, ScriptAction, and Send SNMP Trap Action. For more information about each of these actions, see Foglight actions.
In the Description box, type the action description.
5
Click Add.

From here, you can edit the action parameters as required. For more information, see Editing rule action parameters.

Each rule action includes a set of action parameters that can define its behavior. Some action parameters are mandatory while others are optional.

When you add an action to a rule, you must configure the action’s mandatory parameters to ensure its execution when the rule reaches the severity level for which the action is defined. Action parameters can contain Foglight registry variables, rule-level variables, or any custom value. The data type of the specified value must match the action parameter’s data type.

For example, a command action must have the command name associated with it, and in some cases, one or more environment variables. The command name is a mandatory parameter, while the environment variables are optional parameters. However, failing to specify environment variables related the command prevents the command action from being executed.

NOTE: When the condition of a simple rule is met, the rule enters the Fire state. By default, simple rules do not generate alarms when their conditions are met. Some simple rules that ship with Foglight create observation alarms that are not directly associated with the original rule. This is accomplished by calling the checkObservationAlarms() function in the rule condition. When the condition of a simple rule includes a call to the checkObservationAlarms() function, and the rule includes an email action, in the message body of the resulting email, the following text always precedes the value specified by the mail.message parameter:

The following alarms have been raised. Please use the provided URLs to obtain alarm details.

For more information about the checkObservationAlarms() function, see Using Functions in Conditions and Expressions.

In Foglight, Simple Network Management Protocol (SNMP) trap actions can be configured to forward alarms to an SNMP trap receiver. Trap definitions are specified in a Management Information Base (MIB) file. MIB files contain data structures that define the types of events that are being monitored and controlled.

Configuring SNMP trap actions assumes that you plan on sending SNMP traps from your monitoring environment to an external SNMP trap receiver. The process of forwarding SNMP traps is triggered by rules. This means that a rule that has an SNMP trap action assigned to it can cause Foglight to send an SNMP trap to a trap receiver when the rule’s condition is met.

There are several ways that you can use to configure SNMP trap actions. The simplest and probably most convenient way is to edit the Forward Alarms as SNMP Traps rule that is included with a core installation of Foglight.

This rule relies on the definitions of the MIB file, quest-foglight.mib. Both the Forward Alarms as SNMP Traps rule and the quest-foglight.mib file are included in the Send-SNMP-Trap-Action cartridge, deployed during the Foglight Management Server startup.

Figure 6. You can download the quest-foglight.mib file using the Components for Download dashboard.

This type of configuration involves editing the SNMP community string and the trap receiver’s IP address defined in the Forward Alarms as SNMP Traps rule. When configured, the rule sends traps that are formatted according to the settings specified in the SNMP trap action parameters. The rule contains an entering Send SNMP Trap Action with a set of pre-defined parameters that are compatible with the MIB file.

In addition to editing the SNMP community string and the trap receiver’s IP address, it is possible to define advanced SNMP settings, such as the trap target address or variable bindings using this rule. You can either edit, or copy and edit the Forward Alarms as SNMP Traps rule to meet your needs. Another option is to define SNMP traps in new or existing rules by adding an entering or exiting Send SNMP Trap Action to a rule, and edit the action’s parameters. This process typically requires advanced knowledge of the SNMP protocol and is beyond the scope of this guide. For more details, consult your SNMP documentation.

1
On the navigation panel, under Dashboards, choose Administration > Rules & Notifications > Rule Management.
2
On the Rule Management dashboard, locate the Forward Alarms as SNMP Traps rule entry.
3
Start editing the Forward Alarms as SNMP Traps rule. On the Rule Management dashboard, click the Rule column of the row containing the Forward Alarms as SNMP Traps rule.
4
In the menu, click View and Edit.
5
In the Confirm Edit Core Rule dialog box, click Continue
6
In the Rule Detail dialog box, in the upper-right corner, click Rule Editor.
NOTE: Some browser versions do not support the nested rendering of the Edit Rule page that you are about to access. If you are using those browser versions, click Launch in the display area, as prompted, to open the Edit Rule page in a new window or tab.
The Forward Alarms as SNMP Traps rule is a simple rule, which means that it only contains one state—Fire. The settings for the rule’s Fire state appear by clicking the Fire bar in the Conditions and Actions tab.
On the Conditions and Actions tab, click the Fire bar.
In the Fire pane, open the Action tab.
In the Action tab, in the Actions table, click the Send SNMP Trap Action entry.
10
Edit the CommunityString and TargetAddress action parameters.
Set the CommunityString parameter to contain your SNMP community string of the trap receiver. This test string acts as a password used to authenticate messages. For more information, refer to your SNMP documentation.
Set the TargetAddress parameter to the IP address of the trap receiving computer.
a
In the Action Parameters table, click the Value column of the parameter that you want to edit.
For example, to edit the CommunityString or TargetAddress parameters, in the row containing those entries, click its Value column (initially set to public and localhost, respectively).
The Action Parameter Editor allows you to reference registry or rule-level variables (Variable tab) or to specify a literal string (User Defined tab). The target address of the SNMP receiver and the SNMP community string are not referenced in any system or rule-level variables and do not change over time and are therefore specified as literal text string in the User Defined tab of the Action Parameter Editor dialog box.
b
Open the User Defined tab and type the SNMP community string (CommunityString parameter) or the SNMP trap receiver IP address (TargetAddress parameter), followed by clicking Change in the dialog box.
The Action Parameter Editor dialog box closes and the Action Parameters table refreshes, showing the newly-edited parameter after you edit a parameter value.
In the Edit Rule view, in the lower-left corner of the Condition and Actions tab, click Save All.

In some cases you may need to copy the severity-level variables and actions from an existing severity level of the same rule. Each severity level can have its own actions and severity-level variables.

While you edit rules, any unsaved changes to the severity-level variables or actions that you want to copy will be carried over to the destination severity. For example, if you edit an action for the Warning condition of a rule without saving it, and then proceed to copy that action in the Critical pane, the unsaved edits of the Warning action will be carried over to the Critical severity.

Copying severity-level actions and variables can be useful in situations when those definitions are identical or similar. Instead of writing and validating them for each severity level you can copy existing ones and modify them, if required.

You can associate a rule with an effective schedule or a blackout schedule. An effective period is a schedule during which you want a rule to be evaluated. For example, you might want to set your company’s hours of operation as the effective period for a rule.

You can also set blackout periods for a rule. A blackout is a schedule during which evaluation of the rule is suspended for set intervals. For example, you might want to set the times when regularly scheduled maintenance is performed on a server as the blackout period for a rule.

If a rule has no schedules associated with it, then it is always active. If you only add effective schedules to a rule, then it is automatically inactive at all times other than those specified by the effective schedules. Conversely, if you only add blackout schedules to a rule, then it is automatically active at all times other than those specified by the blackout schedules.

If you add both effective and blackout schedules to a rule, then it will be active only at the times specified by the effective schedules minus the times specified by the blackout schedules. This is because blackout schedules take precedence over effective schedules. For example, suppose you add two schedules to a rule: an effective schedule that runs Monday to Friday, 9 am to 5 pm, and a blackout schedule that runs every Tuesday from 10am to 11am. The rule will be active every Monday, Wednesday, Thursday and Friday from 9 am to 5 pm but will only be active from 9am to 10am and from 11am to 5pm on Tuesdays.

NOTE: Adding the Always entry to the list of blackout schedules does not create a black out for the rule. It has no effect on the rule’s blackout schedule.

Foglight allows you to configure rule behavior to ensure it does not fire repeatedly. Defining the behavior of rule alarms and actions can help you avoid being overwhelmed with alerts when a rule condition is met many times within a short period.

The following options are available:

Fire action if x consecutive evaluations are true. Sometimes, observations are high-strung, causing a single match in the evaluation to lead to more actions than desired. With this option it is possible to enforce a certain number of positive evaluations before a rule finally fires.
Setting this option to x causes the rule’s actions (simple and multiple-severity rules) and alarms (multiple-severity rules only) to execute when the number of evaluations defined by x are true.
Example: A rule that checks the current CPU utilization is evaluated every 5 minutes. To avoid having short spikes leading to a firing rule, you can configure a damper mechanism to prevent actions and alarms from occurring until a certain number of matches is reached, such as, for example, three consecutive evaluations. That means that three times in 15 minutes (because the rule is evaluated every five minutes) the evaluation has to resolve to true before the rule fires.
Fire actions if x out of y evaluations are true. Similar to the above setting, this option allows to enforce a pattern of the evaluation behavior. When the frequency of positive evaluations matters less than their reoccurrence, this option allows for a less strict damper mechanism.
Setting this option to x out of y causes the rule’s actions (simple and multiple-severity rules) and alarms (multiple-severity rules only) to execute after x out of y evaluations are true.
Example: A fixed number of positive evaluations in a row is not missing positives matches, however their pattern of 2-0-2-1-0-2 consecutive positive evaluations is not identified. Setting this option to 4 out of 8 allows for identification of a problem across multiple evaluations while not relying on them being consecutive.
Wait at least [hh:mm:ss] hh:mm:ss after first evaluation. Sometimes when evaluations are performed immediately after a topology object creation, or the Foglight Management Server re-start, a number of false positives can occur. There might be a startup-time factor or the monitored entity simply needs to calm down for a minute or two, before reliable analysis can be performed. This option specifies that the first evaluation and all evaluations in the given time frame afterwards are ignored before evaluation results are considered.
Example: When a new host becomes available online, a high network utilization is expected, while updates are downloaded or application synchronization commences. To avoid having newly-discovered hosts generate alarms on their bandwidth usage, you can specify a time window, for example, 15 minutes, during which the rule evaluating the network conditions is on hold.

Foglight allows you to create flexible rules that can be applied to complex, interrelated data from multiple sources within your distributed system. You can associate several different actions with a rule, configure a rule so that it does not fire repeatedly, and associate a rule with schedules to define when it should and should not be evaluated.

Different types of data can be used in rules, including registry variables, raw metrics, derived metrics, and topology object properties.

There are two types of rules in Foglight: simple rules and multiple-severity rules. A simple rule has a single condition, and can be in one of three states: Fire, Undefined, or Normal. A multiple-severity rule can have up to five severity levels: Undefined, Fatal, Critical, Warning, and Normal.

Rule conditions are regularly evaluated against monitoring data (metrics and topology object properties collected from your monitored environment and transformed into a standard format). Therefore, the state of the rule can change if the data changes. For example, if a set of monitoring data matches a simple rule’s condition, the rule enters the Fire state. If the next set does not match the condition, the rule exits the Fire state and enters the Normal state.

A rule condition is a type of expression that can be true or false. When it evaluates to true, the rule is said to fire, causing any actions that are associated with the rule or severity level to be performed. You can configure a rule to perform one or more actions upon entering or exiting each state. When a multiple-severity rule fires, an alarm also appears in Foglight.

For more information see Configure Rules and Metric Calculations to Discover Bottlenecks .

The Foglight Management Server includes some built-in rules that monitor the health of your application server environment. Rules in this section:

NOTE: The Foglight Management Server also includes a rule that can be used to configure SNMP Trap Actions. For more information about this rule, see Forward Alarms as SNMP Traps rule.

Foglight includes two kinds of trap actions: SNMP Trap Actions and Send SNMP Trap Actions. Both trap action technologies are currently supported, however the Send SNMP Trap Action is a new version of trap actions, and is recommended by Quest over the use of SNMP Trap Actions.

Similar to SNMP Trap Actions, Send SNMP Trap Action can be configured using the Forward Alarms as SNMP Traps rule, described in this topic.

Both trap action technologies are currently supported, however Quest recommends the use of Foglight Trap Actions over SNMP Trap Actions.

This rule monitors the health of all agents in the monitoring environment. It generates an alarm if it finds an agent whose health is deteriorating (Warning) or is down (Critical).

Agent : agentID != "0"

An agent’s health is in decline

Warning

An agent is down

Critical

This rule sends all alarms from Foglight to the Service Discovery and Dashboards product.

The BSM All Events rule includes an entering BSM action which includes two mandatory action parameters: Alarm system event and BSM URL. These parameters must be set in order for the BSM rule to work properly. By default, Alarm system event is set to the alarmEvent rule-level expression, while the BSM URL action parameter points to the BSM URL Foglight registry variable. To ensure this rule works as expected, you need to configure the BSM URL Foglight registry variable to the destination address, followed by enabling this rule (it is disabled by default).

For more information about the Service Discovery and Dashboards, see the product documentation.

None

This rule monitors the credentials that have the Validity Window policy set. It fires when it finds any credentials that are about to expire.

CatalystServer

A credential is currently valid but is to expire in five days or earlier.

Warning

A credential is no longer valid.

Critical

This rule monitors the observations and generates an alarm if the Data Service starts discarding any observations. This can happen when the Foglight Management Server is overloaded, or when there is a difference, or the difference in the system time between the monitored system and the Foglight Management Server. This alarm indicates the server is overloaded and cannot keep up with the incoming data.

CatalystDataService

The Data Service discards one or more observations within a 15 minute interval

Warning

This rule monitors the size of the database, checking whether the database size is higher than the predefined threshold, set by the DBSMon.MaxDatabaseSize registry variable. By default, this value is set to 100 Gb. If required, you can increase this value.

CatalystDatabase

The size of the Foglight database exceeds 75% of the maximum database size.

Warning

The size of the Foglight database exceeds 90% of the maximum database size.

Critical

The size of the Foglight database exceeds 100% of the maximum database size.

Fatal

This rule checks the space that is currently available to the Oracle database against the thresholds defined in the Foglight registry. It generates alarms when the Oracle table space becomes too large. The thresholds for generating alarms are set by the following variables:

Database administrators should provide values for these thresholds in order to get notified when the database starts growing out of bounds.

CatalystTablespace

The size that is available to the Oracle database exceeds the threshold set by the DBSMon.WarningFreeTablespaceSize registry variable.

Warning

The size that is available to the Oracle database exceeds the threshold set by the DBSMon.CriticalFreeTablespaceSize registry variable.

Critical

The size that is available to the Oracle database exceeds the threshold set by the DBSMon.FatalFreeTablespaceSize registry variable.

Fatal

This rule periodically clears old LogFilter alarms.

None

This periodically looks for new agent instances that are connecting to the Foglight Management Server. It rebuilds the topology if it detects new agents.

CatalystServer

This rule directs all scheduled reports to their email recipients. A scheduled report can have one or more email recipients.

None

Checks whether the CPU count of an agent type exceeds the licensed number of agents. It generates a Warning alarm if it finds that the number of monitored hosts an agent is currently monitoring is higher than the number allowed by your license.

AgentTypeLicense

The number of monitored hosts is higher than the number allowed by the license.

Warning

This rule checks the amount of time the Foglight Management Server spends for garbage collection and generates alarms if that time exceeds pre-defined thresholds, defined by a set of registry variables for each severity state: Warning, Critical, and Fatal.

(CatalystServer).jvm.garbageCollectors where name not like '%copy%'

The amount of time spent on garbage collection exceeds the threshold set by the registry variable FMSMon.gcWarn. The default value of that variable is 10.

Warning

The amount of time spent on garbage collection exceeds the threshold set by the registry variable FMSMon.gcCritical. The default value of that variable is 30.

Critical

The amount of time spent on garbage collection exceeds the threshold set by the registry variable FMSMon.gcFatal. The default value of that variable is 90.

Fatal

This time-driven rule checks the validity of the current licenses, and generates alarms if it finds that a license is about to expire within a certain time period.

CatalystServer

A license expires in the number of days set by the LicenseExpirationDaysWarning registry variable. By default, this number is 30.

Warning

A license expires in the number of days set by the LicenseExpirationDaysCritical registry variable. By default, this number is 7.

Critical

A license expires in the number of days set by the LicenseExpirationDaysFatal registry variable. By default, this number is 2.

Fatal

This rule checks the memory that is available to the Foglight Management Server and generates a Critical alarm if the server is in danger of running out of memory, defined as 95% memory utilization. If this alarm is generated and cleared occasionally, this does not indicate any potential problems, however, if the alarm stays active without clearing, or if it is generated and cleared frequently, this indicates that you need to increase the memory allotment.

(CatalystServer).jvm

The amount of memory that is available to the Foglight Management Server exceeds 95% of the total memory usage.

Critical

Checks if any attempts to create topology objects are failing because the topology size limit has been reached. This number is defined by the foglight.limit.instances registry variable whose global default value is set to 10,000. You can change this value if required.

CAUTION: Increasing the default value of the foglight.limit.instances variable may cause performance issues on the Foglight Management Server. If you need to increase this value, contact Quest Support for further instructions.

The setting of this threshold protects against volatile, untuned topology models. This can be often caused by JavaEE Request URL tuning. If this rule fires, in most situations agent tuning is required to make the data less volatile.

CatalystTopologySizeConstraintService

The attempts to create topology objects are failing because the maximum number of topology objects exceeds the value set by foglight.limit.instances.

Warning

This is a template rule that can direct all incoming SNMP traps to an SNMP trap receiver, once the rule’s Send SNMP Trap Action parameters, CommunityString and TargetAddress are set to point to the desired SNMP trap receiver.

You can use this rule as a template when creating rules with SNMP trap actions. For more information about viewing the settings related to SNMP trap actions and their configuration in Foglight, see Configure trap actions .

None

This rule periodically checks whether there are any idle agents. An agent is considered idle if it is running but the Foglight Management Server does not register any data associated with that agent for a pre-defined period of time, defined by a registry variable for each severity state: Warning, Critical, and Fatal

Agent

The agent is idle for the number of hours set by the registry variable IdleAgent.Warning. The default value of that variable is 1.0 hours.

Warning

The agent is idle for a period of time set by the registry variable IdleAgent.Critical. The default value of that variable is 24.0 hours.

Critical

The agent is idle for a period of time set by the registry variable IdleAgent.Fatal. The default value of that variable is 168.0 hours.

Fatal

This rule checks whether at least one instance of the Foglight Agent Manager is running on a monitored host.

Host : detail instanceof RemoteClient

No instance of the Foglight Agent Manager on a monitored host.

Warning

Foglight monitors each service (either implicit or user-defined) for service level compliance. The ServiceLevelEvaluation – FMSServiceSLP rule checks the availability of each service and raises an alarm if the availability is lower than the a predefined threshold during a period of one hour.

FSMServiceLevelPolicy

An average availability during one hour period is below 95%.

Warning

An average availability during one hour period is below 85%.

Critical

An average availability during one hour period is below 70%.

Fatal
