Field Notes from an Alert That Fired Correctly and Was Ignored

The alert had cried wolf for six months, so when it fired truthfully the on-call muted it inside a minute, which was the rational response to its history.

The responder did nothing wrong; muting that alert had been correct 43 consecutive times. The alert had spent its credibility long before the day it earned it.

Rebuilding alert credibility

• Every alert tracks its true-positive rate as a visible metric.
• Alerts below the credibility floor are fixed or deleted, not tolerated.
• Muting an alert requires a reason that feeds the precision review.

Use the audit schema, benchmarks, and contributing guide to keep alerts credible enough to believe on the day it matters.
