Interpretation Notes
- Pair this with load metrics to evaluate scaling lag.
- Frequent scale oscillation indicates threshold or stabilization tuning needs.
- Normal pattern: predictable scale reactions during known traffic peaks.
Limitations
- Text terms may vary by runtime platform version.
- Does not directly expose source metric values for all triggers.
