Monitoring

Built-in monitoring (Prometheus Operator)

The Loki Helm chart can render ServiceMonitors, PrometheusRule recording rules, PrometheusRule alerts, and Grafana dashboards from the upstream loki-mixin:

YAML 
monitoring:
  serviceMonitor:
    enabled: true
  rules:
    enabled: true   # recording rules only
  alerts:
    enabled: true   # alert rules (separate since chart 18.0.0)
  dashboards:
    enabled: true

All monitoring resources are disabled by default.

As of chart 18.0.0, alert rules are managed under monitoring.alerts, not monitoring.rules (which now controls recording rules only). The release-identifying metric label is app_instance by default (monitoring.appInstanceLabelName).

For details on available monitoring keys, refer to the Helm Chart Reference.

Warning

We no longer recommend using the meta-monitoring Helm chart to monitor Loki. The former monitoring.selfMonitoring / Grafana Agent integration was removed in chart 9.0.0. To consolidate monitoring efforts into one Helm chart, Grafana Labs recommends using the Kubernetes monitoring Helm chart. Instructions for setting up the Kubernetes monitoring Helm chart can be found under Manage.
