| Grafana managed alerts |
Clustering
The current alerting system doesn't support high availability. Alert notifications are not deduplicated and load balancing is not supported between instances; for example, silences from one instance will not appear in the other.
Alert evaluation
Grafana managed alerts are evaluated by the Grafana backend. Rule evaluations are scheduled, according to the alert rule configuration, and queries are evaluated by an engine that is part of core Grafana.
Alerting rules can only query backend data sources with alerting enabled:
- builtin or developed and maintained by grafana:
Graphite,Prometheus,Loki,InfluxDB,Elasticsearch,Google Cloud Monitoring,Cloudwatch,Azure Monitor,MySQL,PostgreSQL,MSSQL,OpenTSDB,Oracle, andAzure Data Explorer - any community backend data sources with alerting enabled (
backendandalertingproperties are set in the [plugin.json]({{< relref "../../developers/plugins/metadata.md" >}}))
Metrics from the alerting engine
The alerting engine publishes some internal metrics about itself. You can read more about how Grafana publishes [internal metrics]({{< relref "../../administration/view-server/internal-metrics.md" >}}). See also, [View alert rules and their current state]({{< relref "../../alerting/old-alerting/view-alerts.md" >}}).
