A green uptime check doesn't mean users are happy. Slow checkout, failing webhooks, and rising error rates often show up in metrics and logs long before the homepage returns 500.
Define SLOs with the business
Availability, latency p95, error budget—agree on what “good” means for checkout, login, or API. Alert on SLO burn, not every CPU blip.
Structured logs
JSON logs with request IDs across services make incidents debuggable. Correlate app logs with ingress and database telemetry.
Runbooks, not just pages
Every alert should link to “what to check first.” PagerDuty or Teams integration is useless if the on-call engineer starts from zero.
Bottom line
Observability is a product feature for your platform team. DevFuze sets it up alongside CI/CD—not six months after launch.
