Smarter anomaly detection to reduce false positives:
**Learning Window:** 7 days → 14 days
- Captures weekly patterns (weekday vs weekend)
**Metric-Specific Thresholds:**
CPU:
- Only report if usage >70% AND >2x baseline
- Low CPU variance (5% vs 10%) is not actionable
Memory:
- Report if >80% OR (>1.5x baseline AND >60%)
- Memory is more stable, lower threshold makes sense
Disk:
- Report if >85% usage OR +15 percentage points growth
- Disk problems are critical, use absolute thresholds
Other metrics:
- Use 2x threshold as default
This dramatically reduces 'noise' anomalies while catching
actual problems that need operator attention.
