Guidance for naming metrics, controlling label cardinality, and writing alerting rules in Prometheus, the CNCF metrics and alerting system.

Alerting on user-visible symptoms (errors, latency, SLO burn) rather than internal causes, to reduce noise and page only on things that matter.

Running production systems with no metrics, logs, or alerts, so problems are invisible until users complain and incidents cannot be diagnosed.

So many low-value or noisy alerts fire that responders become desensitized and start ignoring them, including the ones that actually matter.

Write Prometheus alert rules, route and group them in Alertmanager, and deliver notifications to Slack or email.
