Alerts in Fleet Management

The Fleet Management service doesn’t come with out-of-the-box alerts, but it fetches user-created alerts from the Grafana Prometheus instance.

View active alerts

You can view a collector’s active alerts in the Fleet Management interface:

In your Grafana Cloud stack, click Connections > Fleet Management.
Search, filter, or sort to find the alerting collector in your Inventory.
Click on the collector to open the details view drawer and switch to the Alerts tab.

Note
If you don’t see active alerts in a collector’s details view, refer to Alerts don’t appear in app for guidance.

Create new alerts

You can create alerts for collector health issues in Prometheus Alertmanager. Refer to the Alertmanager documentation for tips on using Mimirtool to configure Alertmanager.

When setting up alerts, make sure the following labels are set so that the alerts are properly linked in Fleet Management:

collector_id: The value of this label must match the collector’s unique ID in Fleet Management.
- For Alloy collectors, collector_id should match the id argument in the collector’s remotecfg block.
- For OpenTelemetry Collectors, collector_id should match the service.instance.id set by the OpAMP Supervisor. You can find this value in Name/ID column on the Inventory tab or in the instance_id field of the persistent_state.yaml file in the Supervisor’s storage directory.
severity: The Fleet Management service uses the value of this label to assign a yellow or red health status indicator.
source="fleet-management": The value of the source label must be set to "fleet-management".
