Firing Alerts

The Firing Alerts page shows all active notifications currently being managed by the Alertmanager. Notifications are grouped by label to reduce noise, and you can filter by state, contact point, or Alertmanager instance.

Notification States

Each notification group will be in one of the following states:

State Description
Active The alert is firing and notifications are being delivered to the configured contact point.
Suppressed The alert is firing but notifications are being held back by a Silence or Mute Timing. The alert is still visible here but no messages are being sent.
Unprocessed The alert has been received by the Alertmanager but has not yet been matched to a notification policy.

Viewing Active Notifications

  1. Navigate to Alerting > Firing Alerts.
  2. Use the Search by label bar to filter by a specific label key or value (such as, alertname=high-cpu).
  3. Use the Notification state buttons to filter by Active, Suppressed, or Unprocessed.
  4. Use the Filter by contact point dropdown to show only notifications delivered to a specific destination.
  5. Use Custom group by to regroup the list by a different label (such as, severity or team).

Choosing an Alertmanager

Use the Choose Alertmanager dropdown in the top right to switch between Grafana's built-in Alertmanager and any external Alertmanager instances configured in your environment.

Expanded Alert Detail

Click the > arrow on a notification group to expand it and view full details for each alert instance:

Silencing from Firing Alerts

You can create a silence directly from an active notification without navigating away:

  1. Expand a notification group by clicking the > arrow on the left.
  2. Click the Silence button on the alert instance row.
  3. The silence form will be pre-filled with the alert's labels — adjust the duration as needed.
  4. Click Submit to suppress notifications immediately.
