Use alert suppression

Alert suppression helps you reduce alert noise by ensuring that actions are executed only when they are meaningful. Instead of disabling alerts entirely, you can allow alerts to trigger while adjusting the alert scope to prevent notifications, escalations, or other actions in situations where they are not useful.

Design suppression conditions so that actions only fire when operator intervention is required. If no action is needed, suppression should prevent the alert from generating noise.

Use suppression sparingly and only where it adds value. Overusing suppression can hide important signals, while well-designed suppression rules significantly improve signal-to-noise ratio.

By combining trigger conditions with well-defined suppression conditions, you can maintain full visibility into system state while ensuring that alert actions remain relevant, timely, and actionable.

Suppress expected or acceptable conditions

Configure suppression conditions for situations where alerts are expected and do not require action. For example, suppress alerts for:

Development or test systems
Non-critical devices or interfaces
Known recurring conditions that do not impact operations

Add context to condition-heavy alerts

If your alert depends on multiple factors, use suppression to ensure actions are executed only when the full context is relevant. For example:

Trigger on a performance threshold
Suppress actions when the affected system belongs to a specific category

Avoid redundant notifications

Use suppression to prevent actions when another condition already explains the issue. For example:

Suppress a secondary alert if a higher-level or root-cause condition is already present
Suppress alerts for dependent components when the parent entity is the actual source of the problem

Configure suppression

In the Add/Edit alert wizard, define alert suppression on the Suppression Condition screen. See Define when a triggered alert shouldn’t execute alert actions.

Validate and refine suppression rules
