AlertManager¶

The Alertmanager handles alerts sent by client applications such as the Prometheus server. It takes care of deduplicating, grouping, and routing them to the correct receiver integration such as email, PagerDuty, or OpsGenie. It also takes care of silencing and inhibition of alerts.

Highlights¶

Alertmanager routes alerts to different receivers based on defined rules and labels.
Similar alerts can be grouped together to reduce notification noise.
Duplicate alerts are identified and suppressed, preventing redundant notifications.
Users can temporarily mute specific alerts for maintenance or troubleshooting.
Alerts can be suppressed based on the presence of other active alerts, preventing alert storms.
Alertmanager can be deployed in a cluster for increased reliability.

Quickstart¶

Start an instance with 1-Click, or optionally using your cloud provider’s web/console
Have just a little patience: it does take a couple of minutes for all the background services to start up in your instance. If you get connection refused or site error messages - just wait a moment
Configure your Grafana to use your AlertManager: go to Connections / Datasources and “Add New Datasource” button, where you find the AlertManager datasource and URL https://<your IP/public DNS>:9093 with Basic auth credentials with username admin and and the instance id as password.
