Read what actually happened.

Separate the observed failure, its suspected cause and the action actually taken.

A green monitor closes one observation, not necessarily the customer incident.

Compare like periods and operating conditions before changing the monitoring plan.

Read the denominator, exclusions and monitored path before treating a percentage as service reliability.

Investigate the disagreement before dismissing either the monitor or the customer report.

Treat monitoring as a service with its own access, delivery and ownership dependencies.

Test an isolated authorized condition and label the resulting messages clearly.

Map the replacement responsibility before removing a check that someone may still rely on.

Renew for a capability and response responsibility you still use, not for a reassuring dashboard alone.
