Integrated Alerting

Integrated Alerting lets you know when certain system events occur.

Caution Integrated Alerting is a technical preview and is subject to change.

To activate Integrated Alerting, select PMM→PMM Settings→Advanced Settings, turn on Integrated Alerting and click Apply changes.


  • Alerts are generated when their criteria (alert rules) are met; an alert is the result of an alert rule expression evaluating to true.
  • Alert rules are based on alert rule templates. We provide a default set of templates. You can also create your own.

PMM’s Integrated Alerting is a customized and separate instance of the Prometheus Alertmanager, and distinct from Grafana’s alerting functionality.

    Alert Rule Template parameters

    The parameters used in the template follow a format and might include different fields depending on their type:

    • name (required): the name of the parameter. Spaces and special characters not allowed.
    • summary (required): a short description of what this parameter represents.
    • type (required): PMM currently supports the float type. (More will be available in the future, such as string or bool.)
    • unit (optional): PMM currently supports either s (seconds) or % (percentage).
    • value (optional): the parameter value itself.
    • range (optional): only for float parameters, defining the boundaries for the value.
