Silencing alert notifications

Sometimes, it makes sense to silence alert notifications, such as during maintenance or testing windows.

About this task

You can silence alerts that match the rules you define in the Silence tab. Optionally, you can silence alerts for specific periods that you define. Once silenced, alerts are triggered and displayed on the Alerts page, but email or Webhook notifications are not sent.

Procedure

To create an alert silence rule, complete the following steps:

  1. Navigate to the System > Health > Silence tab.
  2. Click Create > New Alert Silence Rule.
  3. In the Create Alert Silence Rule dialog, perform the following:
    1. Enter a Silence Name for this alert silence rule and provide the Reason why you are creating the alert silence rule.
    2. In the Silence Filters section, select the filters based on your requirements:
      Filter Description
      Clusters Select one or more clusters from the drop-down for which you want the alerts silenced.

      Alert Name Select one or more names from the drop-down you want to silence.
      Source Type Select one or more sources from the drop-down for which you want the alerts silenced.
    3. In the Time Range section, select a date in the Start Date and End Date fields to set the period within which the alert notifications must be silenced.
    4. Enable Suppress if you do not want the alert to persist and appear on the Alerts page.
