max
Trips when a single value in the window exceeds a ceiling threshold.
How it works
Enforces a safety ceiling. It is sensitive to every data point; if any single value crosses the threshold, the breaker fires to prevent system overreach.
When to use
- Critical safety limits (e.g., Memory usage at 95%).
- Catching extreme latency outliers.
- Monitoring resource high-water marks.
When not to use
- Noisy environments where one-off outliers are expected and harmless.
State explanations

No single value has crossed the safety ceiling.
