Reduce alert rule evaluation below 10s

  • What Grafana version and what operating system are you using?
    8.4

  • What are you trying to achieve?
    Reduce minimum alert rule evaluation interval below 10s

  • How are you trying to achieve it?
    Changed unified_alerting_min_interval to 1s

  • What happened?
    Grafana will not boot, error: Failed to start grafana. error: value of setting 'min_interval' should be greater than the base interval (10s)

  • What did you expect to happen?
    The minimum interval to decrease

Is it possible to evalute rules every <10s? I can’t seem to find what the ‘base interval’ is and how to modify it

Hi! I’m afraid It is not possible to reduce the minimum interval below 10 seconds. Do you want alert rules that are evaluated more frequently than every 10 seconds?

I ended up making a backend plugin that solved my issue, but yep originally the goal was to have certain alert rules evaluate every <10s.
