Legacy Grafana alerts

    Out of the box, Grafana still supports legacy dashboard alerts. Legacy Grafana alerts consists of two parts:

    Alert rules - When the alert is triggered. Alert rules are defined by one or more conditions that are regularly evaluated by Grafana. Notification channel - How the alert is delivered. When the conditions of an alert rule are met, the Grafana notifies the channels configured for that alert.

    Legacy aerts have two main components:

    • Alert rule - When the alert is triggered. Alert rules are defined by one or more conditions that are regularly evaluated by Grafana.
    • Notification channel - How the alert is delivered. When the conditions of an alert rule are met, the Grafana notifies the channels configured for that alert.
