Manage silences

Silences stop notifications from getting created and last for only a specified window of time.

Add silences

To add a silence, complete the following steps.

  1. In the Grafana menu, click the Alerting (bell) icon to open the Alerting page listing existing alerts.
  2. On the Alerting page, click Silences to open the page listing existing silences.
  3. From Alertmanager drop-down, select an external Alertmanager to create and manage silences for the external data source. Otherwise, keep the default option of Grafana.
  4. Click New Silence to open the Create silence page.
  5. In Silence start and end, select the start and end date to indicate when the silence should go into effect and expire.
  6. Optionally, in Duration, specify how long the silence is enforced. This automatically updates the end time in the Silence start and end field.
  7. In the Name and Value fields, enter one or more Matching Labels. Matchers determine which rules the silence will apply to.
  8. In Comment, add details about the silence.
  9. In Creator, enter the name of the silence owner or keep the default owner.
  10. Click Create.

Edit silences

To edit a silence, complete the following steps.

  1. In the Grafana menu, click the Alerting (bell) icon to open the Alerting page listing existing alerts.
  2. Click Silences to view the list of existing silences.
  3. Find the silence you want to edit, then click Edit (pen icon).
  4. Make the desired changes, then click Submit to save your changes.

When linking to a silence form, provide the default matching labels and comment via matcher and comment query parameters. The matcher parameter should be in the following format [label][operator][value] where the operator parameter can be one of the following: = (equals, not regex), != (not equals, not regex), =~ (equals, regex), !~ (not equals, regex). The URL can contain many query parameters with the key matcher. For example, to link to silence form with matching labels severity=critical & cluster!~europe-.* and comment Silence critical EU alerts, create a URL https://mygrafana/alerting/silence/new?matcher=severity%3Dcritical&matcher=cluster!~europe-*&comment=Silence%20critical%20EU%20alert.

To link to a new silence page for an external Alertmanager, add a alertmanager query parameter with the Alertmanager data source name.

Remove silences

To remove a silence, complete the following steps.

  1. In the Grafana menu, click the Alerting (bell) icon to open the Alerting page listing existing alerts.
  2. Click Silences to view the list of existing silences.
  3. Select the silence you want to end, then click Unsilence.

Note: You cannot remove a silence manually. Silences that have ended are retained and listed for five days.
