Reducing Alert Fatigue With Smarter Routing Rules

Severity-aware routing and deduplication so on-call engineers only get paged for what actually matters.

When every alert pages everyone, engineers stop reading alerts. Routing by severity and deduplicating noise restores trust in the pager.

Route by Severity

Critical alerts page on-call; warnings go to a channel; informational events stay in a feed. The severity decides the destination.

Routing rule

Critical → PagerDuty (escalate). Warning → Slack #alerts. Resolved → auto-close the incident.

One root cause shouldn't fire fifty pages. Group related alerts into a single incident so on-call sees one actionable signal.

If an alert isn't acknowledged, escalate to the next responder instead of re-paging the same person. Quiet, reliable escalation beats constant noise.

Turn a noisy outage into a clear sequence of cause and effect with the signals that belong on an incident timeline.

Compare error rate and latency across releases to flag regressions minutes after a deploy — and roll back with confidence.

CPU, memory, saturation, and the early-warning signals that precede most host incidents.
