Foglight Evolve 9.2 - 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

Management Server View and Management Server Metrics

The Management Server View dashboard is useful for examining the server performance. It can help you diagnose potential performance problems and identify bottlenecks in your environment.

1
On the navigation panel, under Dashboards, choose Management Server > Servers > Management Server View.
2
Click Choose a Foglight Server and select the server from one or more list entries that appear.
Rule Service: Shows the number of rule and derived metric instances bound to data objects.
Data Service: Shows the ability of the server to keep up with incoming data.
JVM: Shows the memory performance of the JVM in which the server is running.
JDBC Connection Pool: Shows the number of database connections that are in use or available at any time.
Derivation Service: Shows the number of derivation rulettes, errors, and evaluation counts.
Email Sender Service: Shows the number of emails that are sent from the selected Management Server.
FMS Database Size: Shows the size of the database.

Object Groups

Most of the object groups needed for service monitoring already exist. Administrators can use the Object Groups dashboard to classify a group of data and then use the Tier Definition dashboard to subscribe to which data groupings you want to use as tiers. Object groups do not bind to data.

An object group is a mapping to a certain set of data types of the objects you are interested in. Once an object group is defined, its mapping can be evaluated to return these objects. Because the result depends on what exist in Foglight by the time the evaluation is done, its membership list may vary.

Foglight ships with a number of default object groups and subgroups. These groups are marked as Created by Foglight and cannot be changed or deleted.

If an object group is used as a tier, it cannot be deleted. If an object group or object subgroup is used in a rule to define a dynamic group of components in a service, it cannot be deleted.

An object group cannot be used to define a rule in the Service Builder unless it contains more than one subgroup. Conversely, you are not allowed to delete all subgroups from an object group if the object group is used to create a rule to dynamically include a group of components in a service.

1
From the navigation panel under Dashboards, click Services > Object Groups.
The Create Object Group dialog box opens.
4
Ensure the Is Disabled check box is cleared to enable the object group activation.
5
Click Create.

After creating an object group, you need to add one or more subgroups to that group. For more information, see Create an object subgroup.

An object subgroup contains one or more objects, selected using a common criteria, that make up that subgroup.For example you can create a subgroup that contains all agent instances whose names start with “tor”.

The Create Object SubGroup dialog box opens.
Name: Type a name for the object sub-group that is unique in Foglight.
Description: Optional — Type a description of the object subgroup.
Data Type: Type a regular expression that selects the data type of the subgroup. This is a mandatory value. For example, the following expression selects all Foglight agents with the exception of WindowsAgent instances:
Query Conditions: Optional — Type a filter expression that selects specific object instances only. For example, the following expression selects only those object instances that are already selected by the Data Type expression and whose name starts with ‘tor’:
Is Disabled: Ensure the check box is cleared to enable the subgroup activation.
4
Click Test.
5
Click Create.

Use the Tier Definitions dashboard to associate an object group to a tier. A tier is another logical component that references one or more object groups, based on some common criteria. This type of logical structure helps you investigate performance problems associated with multiple objects. For example, to investigate the state of the monitored components within a tier, drill down on a tier and investigate the hosts that are related to it. For more information about services, see the Foglight User Guide.

The object groups that are made available in the Tier Definitions dashboard are based on object groups that were created using the Object Groups dashboard. For more information, see Create an object group.

The Object Groups that you select in the Tier Definitions dashboard appear in the Tier drop down list when selecting a new local or global service using the Service builder dashboard. These tiers are also used in the Service Operations Console, where they show service breakdown by tier.

NOTE: New tiers are hidden by default in the Service Operations Console. To display a new tier, in the Service Operations Console, click Customize Service Operations Console, open the Tier Selector tab, and ensure the newly-created tier is selected. For more information about the Service Operations Console, see the related help page.

On the navigation panel under Dashboards, click Services > Tier Definition.

The FMS Overview view is a starting point for performance analysis of the Foglight Management Server. It displays information about the database activity, data service performance, JVM performance, and server load in one unified view.

In federated environments, explore the diagnostics for each individual server: Federation Master, Federation Child, or a standalone Foglight Management Server. To do that, click Choose a Foglight Server and select a host from the list that appears.

This view provides more information on:

Data load summary (Data Service, Inserts per 5 minutes views). In the Inserts per 5 min embedded view, num_rows_inserted_per5min shows the number of rows inserted every five minutes, while avg_insert_per5min shows one-hour average of num_rows_inserted_per5min. Spikes on the Data Service embedded view often indicate some kind of data processing lull such as a high amount of incoming data (seen as an increase in batchesProcessed), or insufficient resources to process incoming data decrease in batchesDiscarded).
Whether there is enough memory (JVM Memory Usage view). In this view, memory_usage shows the heap memory usage, totalMemory shows the amount of total heap memory, and freeMemory is the free heap memory. A sawtooth on the JVM memory graph is normal, but if the amount of memory freed by a garbage collect (such as the height of the sawtooth) is small, you may need more memory on your system. A large topology results in a high amount of incoming data and a decrease in free memory. The amount of free memory should never be zero. If it does reach zero this is an indication to adjust the server configuration.
Whether the load on the server is too high (Server Load Status view). Server load is mostly determined by the memory usage in the JVM old generation. If the server runs out of memory it will go into an “overloaded” state. A server can be in this state and have some memory available in the JVM new generation. If that is the case, the server discards incoming agent data but can continue to service browser interface requests to some degree. If the server remains to be overloaded, it likely needs to be re-configured to have more memory available, or less workload coming from the browser interface and/or the agents.

Database insert spikes, slow processing

Incoming data spikes (batchesProcessed increases), slow processing (batchesDiscarded increases)

Too large topology, too much incoming data (freeMemory increases)

Load is higher than 0.7

The Agents view is designed to see what agents you are running, listed by type. By selecting agent types in the tree, a graph showing the number of agents as a function of time is plotted. This graph is handy for viewing changes to the agents, for example if a number of agents that you did not know about were added, or checking if old agents are properly removed.

1
From the navigation panel, click Dashboards > Management Server > Diagnostic > Performance.
2
In the display area, click FMS Overview, and in the list that appears, select Agents.
3
To view agent connectivity, in the Agent Type column, drill-down to the agent type to view its connectivity.

The Baseline Measurements view shows internal database I/O statistics related to baseline computation. A metric baseline is the expected metric range for the given time period. When configured, IntelliProfile computes baselines for metrics, and stores that data in the database.

1
From the navigation panel, click Dashboards > Management Server > Diagnostic > Performance.
2
In the display area, click FMS Overview, and in the list that appears, select Baseline Measurements.
The Baseline Measurements view appears in the display area.
Table 17. Look for the following types of information in the Baseline Measurements view.

High peaks in the graph usually indicate an impact on the database performance, depending on the database capabilities.

High peaks in the graph usually indicate an impact on the database performance, depending on the database capabilities.

High values in the graph may be a sign that baselining activities have a high impact on the database performance, depending on the database capabilities.

This graph shows zero values at all times, unless baseline profiles are explicitly removed for trouble-shooting purposes, usually requiring manual intervention.

This graph shows zero values at all times, unless baseline profiles are explicitly removed for trouble-shooting purposes, usually requiring manual intervention.

Normally these values should correspond to those appearing in the Store Call Count graph. If they are greater that means that some attempts failed due to database-related errors.

High peaks in the graph usually indicate an impact on the database performance, depending on the database capabilities.

High peaks in the graph usually indicate an impact on the database performance, depending on the database capabilities.

Outstanding baseline management operations can include enabling or disabling baselines for a particular metric. This graph can be expected to show zero values at all times.

The Connectivity view shows the Foglight connectivity for the JDBC connection pool and the user session count. It summarizes the database connection state from the perspective of the Foglight Management Server. By looking at this view, you can determine if there are enough JDBC connections to service application requests.

1
From the navigation panel, click Dashboards > Management Server > Diagnostic > Performance.
2
In the display area, click FMS Overview, and in the list that appears, select Connectivity.
The Connectivity view appears in the display area.

Overused pool indicates a slow database.

High number of sessions results in a high browser interface load, indicating a slow browser interface/server.

The Database Overview view displays the metrics that represent the reads, inserts, and updates of the database rows. These metrics can be used in performance load tests to track the unit load.

Contents of this view includes a drop down to select the host name. Here, you can select a Federation Master, Federation Child, or standalone server. To do that, click Choose a Foglight Server and select a host from the list that appears. It also contains the following embedded views:

The name of the metrics that contain database reads, inserts, and updates depend on the type of the supported database that Foglight uses to store information, as indicated in the following table.

num_rows_deleted

num_rows_inserted

num_rows_updated

innodb_rows_inserted

innodb_rows_inserted_per5min: #innodb_rows_inserted# * 300

avg_inserts_per5min: avg(#innodb_rows_inserted_per5min for 60 minutes#)

qa_db_inserts : select sum(inserts) from sys.dba_tab_modifications where TABLE_OWNER='xxxx'

delta_db_inserts: delta(#qa_db_inserts from QA_DB_INSERTS_Agent_Table_DB_INSERT_COUNT#)

delta_avg_per5min: avg(#delta_db_inserts for 60 minutes#)

From the navigation panel, click Dashboards > Management Server > Diagnostic > Performance.
2
In the display area, click FMS Overview, and in the list that appears, select Database Overview.
The Database Overview view appears in the display area.

High number of database operations may indicate a possible database bottleneck. The cause could be related to a problem on the server sid, such as topology changes.

High load may indicate a possible database bottleneck. Check the database specifications.

May indicate a dirty database buffer, possibly because the innodb pool buffer is too small.

Check if there is anything more than row operations.

This view shows the invocation counts of and time spent on garbage collection. It contains two embedded views:

Copy: This view shows the activity of the ParNew garbage collector, used to reclaim memory in the JVM new generation part of the heap. In most cases, there is no need to be concerned with the data on this view unless the numbers become unreasonable (one hour or higher).
ConcurrentMarkSweep: This view shows the activity of the ConcurrentMarkSweep garbage collector, used to reclaim memory in the JVM old generation part of the heap. In general, the values appearing on this view should stay low. An occasional spike does not indicate any problems (such as once a day). If spikes become frequent, the Foglight Management Server memory allocation may need to be adjusted (for example, by balancing the size of new and old generations). In some cases it might be required to increase the overall Foglight Management Server heap.

1
From the navigation panel, click Dashboards > Management Server > Diagnostic > Performance.
2
In the display area, click FMS Overview, and in the list that appears, select Garbage Collector.
The Garbage Collector view appears in the display area.

The Java Virtual Machine (JVM) view provides full details on the JVM memory activity. This view is particularly useful if you are performing detailed JVM tuning for the different memory spaces.

To find out more about the JVM heap generation, observe the spikes on the embedded views. Big spikes with a slow climb are better than small spikes (too little available memory) or a quick climb (frequent garbage collection).

1
From the navigation panel, click Dashboards > Management Server > Diagnostic > Performance.
2
In the display area, click FMS Overview, and in the list that appears, select Java Virtual Machine Memory.
The Java Virtual Machine Memory view appears in the display area.

This view shows the number of rulettes (rule instances) that are bound to specific object instances. This view is useful for understanding the environment complexity.

The Rulette and Topology view shows how many rules and rule instances are running. Many rulettes, especially as a function of the number of objects, can indicate that you are overloading your server or if some old rules are still running.

This view highlights the data and metrics that are being processed in time or getting discarded.

The Service - Data & Message view shows details on data handling of the Foglight Management Server such as the number of skipped messages and the number of discarded metrics. The top-right embedded view shows the percentage of data that is dropped by the server over time, while the top-left embedded view shows the counts of total and skipped messages over time. A high percentage of dropped data can often indicate a server overload. The embedded view in the bottom right is useful for indicating how long data processing is expected to take. If that value grows over time, that is a good indication that the Foglight Management Server cannot keep up with the load from the agents.

Some Foglight dashboards have reports associated with them. This allows you to run a report based on the current dashboard. You can generate the report using the Reports menu in the top-right corner.

The Performance Overview dashboard and Management Server View are associated with the Management Server Performance Summary Report. Run this report by choosing Management Server Performance Summary Report from the Reports menu, and specifying the input parameters in the report wizard.

The report wizard provides more information about the Management Server Performance Summary Report and instructions on how to set the input values. For more information about reports in Foglight, see the Foglight User Help.

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

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.

From the command-line, change directories (cd) to the directory where you want to install Foglight.
cd <installation_dir>/bin
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.
