Golden signals still earn their keep
Latency, traffic, errors, and saturation remain a compact set for user-facing services. Start there before importing every vendor “recommended dashboard.” Slice latency by meaningful dimensions—tenant, region, build id—not fifty pre-canned percentiles nobody looks at.
Structured logs and correlation IDs
Unstructured printf debugging in production logs wastes everyone’s time. Emit JSON or key=value lines with stable field names; propagate a request ID from edge to database so integrations remain debuggable when they fail mid-chain.
Tracing where complexity lives
Traces pay off when a user request touches more than two services or async workers. Sample intelligently: keep errors and slow spans at higher rates. Store enough context for triage, not enough PII to create a new compliance problem.
Alert design is product design
Each alert should imply an action and an owner. If the correct response is “ignore until Monday,” it is not a page—it is a ticket or a report. Review alert load quarterly; sympathy for on-call is part of morale and workload.
Self-hosted stacks
When you run your own metrics backend, plan retention and cardinality up front. Unbounded label combinations explode storage and slow queries—guardrails beat heroic compaction jobs later.
