Define freshness
Every signal should identify its source and observation time. A disconnected collector is not the same as a quiet server.
Use workload baselines
Traffic from scheduled backups, promotions, crawlers and client reconnects can legitimately create bursts. Compare patterns with normal host activity.
Start in observation mode
Validate policy thresholds without enforcing broad blocks. An event review should retain policy context and show the evidence behind the decision.
Do not over-trust dashboards
Charts are presentation. The underlying timestamps, measured signals and collector health determine how much confidence an operator should place in them.
