slope
Trips when the long-term trajectory of a metric indicates a steady crawl in a bad direction.
How it works
Identifies long-term trajectory over an extended horizon. It detects gradual degradation or "slow leaks" that absolute thresholds might miss.
When to use
- Detecting slow memory leaks.
- Identifying gradual database performance degradation.
- Forecasting resource exhaustion (e.g., disk space).
When not to use
- Fast-moving metrics requiring immediate protection from spikes.
