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

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.
