Logs, metrics, traces, and alerts are part of \"done,\" not a follow-up ticket.\n\n## When to Use\n\n- Adding or changing a service boundary, request handler, job, or external call\n- Code paths that can fail partially, retry, time out, or degrade\n- Any change whose health you would want to confirm during a [[staged-rollout]]\n\nSkip only for changes with no runtime behavior (docs, pure refactors with identical I/O, config-only edits).\n\n## Process\n\nApply each layer to the change.\n\n1. **Structured logging.** Emit machine-parseable events (key-value / JSON), not interpolated prose. Attach the correlation/trace id and the dimensions you'd filter on (tenant, route, outcome). Log decisions and failures, not control flow.\n2. **RED metrics.** For every request-serving surface, instrument the three:\n   - **Rate** — requests per second handled\n   - **Errors** — failed requests per second (and the error class)\n   - **Duration** — latency distribution (histogram, so you get p50/p95/p99 — never a single mean)\n3. **Trace spans.** Wrap each external boundary (DB query, RPC, queue, third-party API) in a span that propagates context. Spans turn \"the request was slow\" into \"the request was slow *here*.\"\n4. **Symptom-based alerts.** Alert on user-visible symptoms (error rate breached, latency SLO burning), **not** on causes (CPU high, pod restarted). Causes generate noise; symptoms generate pages worth waking for. Each alert names the symptom and points at the dashboard/runbook.\n\n## Rationalizations\n\n| Excuse | Reality |\n|--------|---------|\n| \"I'll add metrics once it's in prod\" | The first incident is the worst time to discover you're blind. Shift Left. |\n| \"The mean latency is fine\" | A mean hides the p99 tail where users actually hurt. Use a histogram. |\n| \"There are already logs\" | Unstructured logs you can't query are not observability. Structure them. |\n| \"I'll alert on CPU and disk\" | Cause-based alerts page you for non-problems and miss real ones. Alert on symptoms. |\n| \"Tracing is a separate project\" | One span around each boundary is minutes of work and the only thing that localizes latency. |\n\n## Red Flags\n\n- Latency reported as a single average instead of a distribution\n- Alerts wired to CPU, memory, or restart counts rather than user-visible symptoms\n- `log.info(\"processing \" + thing)` style string interpolation instead of structured fields\n- An external call (DB, API, queue) with no span around it\n- \"We'll add observability after launch\" in the plan\n\n## Verification\n\nCite concrete evidence — names and locations, not intentions:\n\n- [ ] Structured log events added at decision/failure points, carrying the correlation id (name the events)\n- [ ] Rate, Error, and Duration metrics emitted for each request surface; Duration is a histogram (name the metrics)\n- [ ] A trace span wraps every external boundary the change touches (name the spans)\n- [ ] At least one symptom-based alert defined against an SLO, pointing at a dashboard/runbook (name the alert)\n","tagline":"Instrument a change with structured logging, RED metrics, trace spans, and symptom-based alerts - use while building the change, not after an incident proves it was unobservable","category":"design-creative","commerce":{"type":"unknown","billing":"unknown","amount":null,"currency":null,"sourceUrl":null,"checkedAt":null,"runtime":"unknown","purchaseUrl":null,"checkout":"external","purchaseRequiresUserConsent":true},"tags":["agent-skill"],"author":"etr","verified":false,"attribution":{"status":"registry_indexed","statusLabel":"Registry indexed","shortLabel":"REGISTRY INDEXED","sourceLabel":"github candidate review","sourceDetail":"etr/groundwork","creatorName":"etr","creatorUrl":"https://github.com/etr","sourceUrl":"https://github.com/etr/groundwork/tree/main/skills/instrument-observability","indexedBy":"OpenAgentSkill community index","claimUrl":"https://www.openagentskill.com/skills/etr-instrument-observability#claim-this-skill","claimCta":"Claim this skill","trustNote":"This listing was indexed from public sources and is not marked official until a maintainer claim is approved.","publicNote":"Attribution links to the public repository or creator profile.
