Customizing Alarms for Foglight for SQL Server Rules

* 
NOTE: Foglight 7.1.0 introduces Alarm Templates, which provide a simplified method for customizing alarm rules and applying them to agents. As part of this change, the Sensitivity Level feature has been deprecated.

Many Foglight for SQL Server rules trigger alarms. To improve your monitoring experience, you can use alarm templates to customize when alarms are triggered and whether they are reported. You can also set up email notifications.

This section covers the following topics:

•
Introducing the Alarms View
•
Viewing Alarm Sensitivity Levels for Unassigned Agents
•
Modifying Alarm Templates
•
Configuring Email Notifications
•
Cloning Agent Settings
•
Reviewing Rule Definitions

Introducing the Alarms View

The Alarms view enables you to modify global settings and agent-specific settings for alarms.

To open the Alarms view:
1
Open the Administration dashboard as described in Opening the Databases Administration Dashboard .
2
Click Alarms.
The list of agents that you selected on the Databases dashboard is shown in the upper right corner of the view.
3
From the Alarms view, you can complete the following tasks:
•
Viewing Alarm Sensitivity Levels for Unassigned Agents
•
Modifying Alarm Templates
•
Configuring Email Notifications
•
Cloning Agent Settings

Viewing Alarm Sensitivity Levels for Unassigned Agents

In previous versions, Foglight for SQL Server offered four sensitivity levels that controlled which alarms were reported:

•
Essential — Store and display only critical or fatal alarms.
•
Normal — Store and display most alarms — essential and best practices; only critical and fatal statistical alarms.
•
Tuning — Store and display all SQL Server alarms sent to Foglight.
•
Performance — Store and display only availability and SQL PI related alarms.

This feature has been deprecated in Foglight 7.1.0. These sensitivity levels can no longer be changed, but for agents that have not been assigned to an alarm template, you may view a report detailing the sensitivity levels previously configured.

To view the sensitivity level used by an agent:
* 
NOTE: You may only view sensitivity levels for an agent that has not been assigned an alarm template.
1
In the Alarms view, click View sensitivity level as PDF in the upper right corner.
A Rules Sensitivity Report will be displayed.

Modifying Alarm Templates

Foglight 7.1.0 uses alarm templates to gather alarm rules into a domain-specific template that is easily modified and applied to targets. You can customize how the alarms generated by the default Foglight for SQL Server rules are triggered and displayed in by assigning alarm templates via the Alarm Template Settings tab. You can apply an existing template, create a new template using an existing template as reference, or create a template based on an agent. All changes to alarm templates apply to the selected agents.

Refer to Viewing, Creating, and Managing Alarm Templates in the Foglight 7.1.0 User Guide for more information.

 

* 
IMPORTANT: Avoid editing Foglight for SQL Server rules in the Administration > Rules & Notifications > Rule Management dashboard. Default rules may be modified during regular software updates and your edits will be lost. Always use the Alarm Templates dashboard.
Figure 31. Use the Alarms view to assign alarm templates.

The Alarms list controls the contents displayed to the right and the tasks that are available.

•
All Alarms – Displays all rules with configured alarms and indicates whether alarms are enabled. In this view, you can enable or disable alarms for all the rules at once. You can also set email notifications and define mail server settings.W hen viewing all alarms, the Alarm Template Settings tab is displayed, enabling configuration of alarm templates.
•
Category of rules – Displays a set of related rules with configured alarms. In this view, you can set email notifications for the category of rules.
•
Rule name – Displays the Email Notification Status for the selected rule. If the rule has multiple severity levels, displays the notification configured for each severity level. In this view, you can enable or disable email notifications for the alarm and edit alarm messages.

You can complete the following tasks:

•
Assign an Alarm Template to selected agents
•
Modifying alarms and threshold values

Your changes are saved separately and applied over the default rules. This protects you from software upgrades that may change the underlying default rules.

Assign an Alarm Template to selected agents

You can override the alarm rules for the selected agents by assigning an alarm template. You can use the template to enable or disable alarms for all rules or an individual rule, or to change the threshold values of an alarm rule.

To see descriptions of the rules, follow the steps described in Reviewing Rule Definitions .

To assign an existing alarm template:
1
In the Alarms view, click the Alarm Template Settings tab.
2
Select Assign a template to selected agent(s),
3
Do one of the following:
•
Select an alarm template from the drop-down.
•
Click Save and Navigate.
OR
•
Select Create a new template from the drop-down. This will allow you to create a new template based of an existing template.
•
In the Clone from field, select the template to copy.
•
Enter a name for the new template.
•
Click Save and Navigate.
4
The template will be displayed in the Alarm Template dashboard. Refer to Viewing, Creating, and Managing Alarm Templates in the Foglight 7.1.0 User Guide for more information on editing alarm templates.
Modifying alarms and threshold values

You can and should modify the thresholds associated with alarms to better suit your environment. If you find that alarms are firing for conditions that you consider to be acceptable, you can change the threshold values that trigger the alarm. You can also enable or disable severity levels to better suit your environment.

When a rule has severity levels, a Threshold section appears in the Alarm Settings tab showing the severity levels and bounds by agent. For an example, see the DBSS - Worker Thread rule. The threshold values corresponds to the lower bounds shown in this table. Many rules, such as Baseline rules, do not have severity levels and thresholds.

When editing thresholds, ensure that the new values make sense in context with the other threshold values. For most metrics, threshold values are set so that Warning < Critical < Fatal. However, in metrics where normal performance has a higher value, such as DBSS - Buffer Cache Hit Rate, the threshold values are reversed: Warning > Critical > Fatal.

To change alarm status and threshold values:
* 
IMPORTANT: The procedure below is a summary. Refer to Viewing, Creating, and Managing Alarm Templates in the Foglight 7.1.0 User Guide for more information on editing alarm templates for more information on working with alarm templates.
1
In the Navigation panel, click Alarm Templates.
2
If you have previously configured an alarm template, select that template.
Otherwise, click the Factory Template to view the default rules. Duplicate the factory template to make an editable copy, selecting the appropriate domains.
3
Click the appropriate domain tab (SQL Server, SQL Analysis Services, etc).
4
Scroll or search to find the alarm rule you want to edit. Click the rule to select it.
5
Edit the rules using the procedure described in Viewing, Creating, and Managing Alarm Templates in the Foglight 7.1.0 User Guide
