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.
