min

Trips when a single value in the window falls below a floor threshold.

How it works

Enforces a performance floor. It ensures a metric remains above a baseline, functioning as a dead-man switch for system activity.

When to use

  • Detecting zero-traffic outages on critical paths.
  • Monitoring baseline performance for heartbeats.
  • Ensuring resources remain above a minimum floor (e.g., free disk space).

When not to use

  • Metrics that naturally go to zero during maintenance or low-traffic periods.
