Silencing alert notifications

Optionally, you can configure silences to temporarily suppress alert notifications. Each silence suppresses the notifications for an alert rule at one or more severities. You can silence an alert rule on the entire grid, a single site, or a single node.

Before you begin

About this task

Because alarms and alerts are independent systems, you cannot use this functionality to suppress alarm notifications.

Steps

  1. Select Alarms. Then, in the Alerts (Preview) section of the menu, select Silences.
    The Silences page appears.
    Alerts > Silences page
  2. Select Create.
    The Create Silence dialog box appears.
    Alerts > Create Silence
  3. Select or enter the following information:
    Field Description
    Alert Rule The name of the alert rule you want to silence. You can select any default or custom alert rule, even if the alert rule is disabled. Select All rules if you want to silence all alert rules using the criteria specified in this dialog box.
    Description Optionally, a description of the silence. For example, describe the purpose of this silence.
    Duration How long you want this silence to remain in effect, in minutes, hours, or days. A silence can be in effect from 5 minutes to 365 days.
    Severity Which alert severity or severities should be silenced. If the alert is triggered at one of the selected severities, no notifications are sent.
    Nodes Which node or nodes you want this silence to apply to. You can suppress an alert rule on the entire grid, a single site, or a single node. If you select the entire grid, the silence applies to all sites and all nodes. If you select a site, the silence applies only to the nodes at that site.
    Note: You cannot select more than one node or more than one site for each silence. You must create additional silences if you want to suppress the same alert rule on more than one node or more than one site at one time.
