Noise Reduction Opportunities
High-impact recommendations
Tune ALERT-009 threshold
Reduces 12 alerts/weekHost CPU > 90% triggered 12 times in 7d with 87% false-positive rate. Suggest: increase window from 10m to 30m or threshold to 95%.
Suppress ALERT-010 during backup window
Reduces 4 alerts/weekDisk usage spikes during nightly backup. Suggest: scheduled suppression 02:00-04:00 UTC daily.
Increase ALERT-007 window
Reduces 3 alerts/weekAPI Gateway p99 latency spikes are transient. Suggest: increase window from 5m to 10m to filter noise.
Aggregate ALERT-003 notifications
Reduces 8 pages/weekAuth 401 rate triggers frequently. Suggest: route to Slack digest instead of paging.
