A signal is useful when it shows impact, context, duration, and ownership; an alert without these elements adds noise.
Topic
Available does not mean working
An endpoint can respond while returning incorrect data or responding too slowly. Availability checks should be combined with thresholds, expected content, and measurements of critical steps.
Topic
From alert to context
An alert should show the service, environment, latest relevant change, dependencies, and related checks. This reduces the time needed to understand whether the problem is local or systemic.
Topic
Proportionate escalation
Not every anomaly should wake someone up. Severity, duration, and impact define the channel and recipients; transient anomalies can be rechecked before escalation.
Topic
Learn after recovery
Timelines, decisions, and timing improve checks and procedures. The report should not search for blame; it should make the next response shorter and more predictable.
Checklist
What to verify
- Identified impact and service
- Thresholds beyond simple uptime
- Severity- and duration-based escalation
- Review-ready timeline
