You treat every unobserved production system as a liability — instrument proactively, correlate signals to diagnose, and never consider a feature done until it is observable.\n\n**Orchestration mode:** Fan out the five signal-specific sub-agents described in Audit mode (metrics, logging, tracing, profiling, RUM) for auditing observability coverage across a codebase, and merge their coverage findings. On Claude Code, use `ultracode` to opt into multi-agent orchestration explicitly.\n\n**Modes:**\n\n- **Coding / instrumentation** (default): Add observability to new or existing code — declare metrics, add spans, set up structured logging, wire pprof toggles. Follow the sequential instrumentation guide.\n- **Review mode** — reviewing a PR's instrumentation changes. Check that new code exports the expected signals (metrics declared, spans opened and closed, structured log fields consistent). Sequential.\n- **Audit mode** — auditing existing observability coverage across a codebase. Launch up to 5 parallel sub-agents — one per signal (metrics, logging, tracing, profiling, RUM) — to check coverage simultaneously.\n\n> **Community default.** A company skill that explicitly supersedes `samber/cc-skills-golang@golang-observability` skill takes precedence.\n\n# Go Observability Best Practices\n\nObservability is the ability to understand a system's internal state from its external outputs. In Go services, this means five complementary signals: **logs**, **metrics**, **traces**, **profiles**, and **RUM**. Each answers different questions, and together they give you full visibility into both system behavior and user experience.\n\nWhen using observability libraries (Prometheus client, OpenTelemetry SDK, vendor integrations), refer to the library's official documentation and code examples for current API signatures.\n\n## Best Practices Summary\n\n1. **Use structured logging** with `log/slog` — production services MUST emit structured logs (JSON), not freeform strings\n2. **Choose the right log level** — Debug for development, Info for normal operations, Warn for degraded states, Error for failures requiring attention\n3. **Log with context** — use `slog.InfoContext(ctx, ...)` to correlate logs with traces\n4. **Prefer Histogram over Summary** for latency metrics — Histograms support server-side aggregation and percentile queries. Every HTTP endpoint MUST have latency and error rate metrics.\n5. **Keep label cardinality low** in Prometheus — NEVER use unbounded values (user IDs, full URLs) as label values\n6. **Track percentiles** (P50, P90, P99, P99.9) using Histograms + `histogram_quantile()` in PromQL\n7. **Set up OpenTelemetry tracing on new projects** — configure the TracerProvider early, then add spans everywhere\n8. **Add spans to every meaningful operation** — service methods, DB queries, external API calls, message queue operations\n9. **Propagate context everywhere** — context is the vehicle that carries trace_id, span_id, and deadlines across service boundaries\n10. **Enable profiling via environment variables** — toggle pprof and continuous profiling on/off without redeploying\n11. **Correlate signals** — inject trace_id into logs, use exemplars to link metrics to traces\n12. **A feature is not done until it is observable** — declare metrics, add proper logging, create spans\n13. **[awesome-prometheus-alerts](https://samber.github.io/awesome-prometheus-alerts/) provides ~500 ready-to-use alerting rules** organized by technology for infrastructure and dependency monitoring\n\n## Cross-References\n\nSee `samber/cc-skills-golang@golang-error-handling` skill for the single handling rule. See `samber/cc-skills-golang@golang-troubleshooting` skill for using observability signals to diagnose production issues. See `samber/cc-skills-golang@golang-security` skill for protecting pprof endpoints and avoiding PII in logs. See `samber/cc-skills-golang@golang-context` skill for propagating trace context across service boundaries. See `samber/cc-skills@promql-cli` skill for querying and exploring PromQL expressions against Prometheus from the CLI.\n\n### Go 1.26+: slog multi-handler\n\nFor simple fan-out to multiple slog handlers, prefer stdlib `slog.NewMultiHandler` before adding third-party handler-composition dependencies.\n\n```go\nlogger := slog.New(slog.NewMultiHandler(\n    slog.NewJSONHandler(os.Stdout, nil),\n    auditHandler,\n))\n```\n\nUse third-party slog handler libraries only when the stdlib handler composition is insufficient.\n\n## The Five Signals\n\n| Signal | Question it answers | Tool | When to use |\n| --- | --- | --- | --- |\n| **Logs** | What happened? | `log/slog` | Discrete events, errors, audit trails |\n| **Metrics** | How much / how fast? | Prometheus client | Aggregated measurements, alerting, SLOs |\n| **Traces** | Where did time go? | OpenTelemetry | Request flow across services, latency breakdown |\n| **Profiles** | Why is it slow / using memory? | pprof, Pyroscope | CPU hotspots, memory leaks, lock contention |\n| **RUM** | How do users experience it? | PostHog, Segment | Product analytics, funnels, session replay |\n\n## Detailed Guides\n\nEach signal has a dedicated guide with full code examples, configuration patterns, and cost analysis:\n\n- **[Structured Logging](references/logging.md)** — Why structured logging matters for log aggregation at scale. Covers `log/slog` setup, log levels (Debug/Info/Warn/Error) and when to use each, request correlation with trace IDs, context propagation with `slog.InfoContext`, request-scoped attributes, the slog ecosystem (handlers, formatters, middleware), and migration strategies from zap/logrus/zerolog.\n\n- **[Metrics Collection](references/metrics.md)** — Prometheus client setup and the four metric types (Counter for rate-of-change, Gauge for snapshots, Histogram for latency aggregation). Deep dive: why Histograms beat Summaries (server-side aggregation, supports `histogram_quantile` PromQL), naming conventions, the PromQL-as-comments convention (write queries above metric declarations for discoverability), production-grade PromQL examples, multi-window SLO burn rate alerting, and the high-cardinality label problem (why unbounded values like user IDs destroy performance).\n\n- **[Distributed Tracing](references/tracing.md)** — When and how to use OpenTelemetry SDK to trace request flows across services. Covers spans (creating, attributes, status recording), `otelhttp` middleware for HTTP instrumentation, error recording with `span.RecordError()`, trace sampling (why you can't collect everything at scale), propagating trace context across service boundaries, and cost optimization.\n\n- **[Profiling](references/profiling.md)** — On-demand profiling with pprof (CPU, heap, goroutine, mutex, block profiles) — how to enable it in production, secure it with auth, and toggle via environment variables without redeploying. Continuous profiling with Pyroscope for always-on performance visibility. Cost implications of each profiling type and mitigation strategies.\n\n- **[Real User Monitoring](references/rum.md)** — Understanding how users actually experience your service. Covers product analytics (event tracking, funnels), Customer Data Platform integration, and critical compliance: GDPR/CCPA consent checks, data subject rights (user deletion endpoints), and privacy checklist for tracking. Server-side event tracking (PostHog, Segment) and identity key best practices.\n\n- **[Alerting](references/alerting.md)** — Proactive problem detection. Covers the four golden signals (latency, traffic, errors, saturation), [awesome-prometheus-alerts](https://samber.github.io/awesome-prometheus-alerts/) provides ~500 ready-to-use rules by technology, Go runtime alerts (goroutine leaks, GC pressure, OOM risk), severity levels, and common mistakes that break alerting (using `irate` instead of `rate`, missing `for:` duration to avoid flapping).\n\n- **[Grafana Dashboards](references/dashboards.md)** — Prebuilt dashboards for Go runtime monitoring (heap allocation, GC pause frequency, goroutine count, CPU). Explains the standard dashboards to install, how to customize them for your service, and when each dashboard answers a different operational question.\n\n## Correlating Signals\n\nSignals are most powerful when connected. A trace_id in your logs lets you jump from a log line to the full request trace. An exemplar on a metric links a latency spike to the exact trace that caused it.\n\n### Logs + Traces: `otelslog` bridge\n\n```go\nimport \"go.opentelemetry.io/contrib/bridges/otelslog\"\n\n// Create a logger that automatically injects trace_id and span_id\nlogger := otelslog.NewHandler(\"my-service\")\nslog.SetDefault(slog.New(logger))\n\n// Now every slog call with context includes trace correlation\nslog.InfoContext(ctx, \"order created\", \"order_id\", orderID)\n// Output includes: {\"trace_id\":\"abc123\", \"span_id\":\"def456\", \"msg\":\"order created\", ...}\n```\n\n### Metrics + Traces: Exemplars\n\n```go\n// When recording a histogram observation, attach the trace_id as an exemplar\n// so you can jump from a P99 spike directly to the offending trace\nobs := histogram.WithLabelValues(\"POST\", \"/orders\")\nif eo, ok := obs.(prometheus.ExemplarObserver); ok {\n    eo.ObserveWithExemplar(duration, prometheus.Labels{\"trace_id\": traceID})\n} else {\n    obs.Observe(duration)\n}\n```\n\n## Migrating Legacy Loggers\n\nIf the project currently uses `zap`, `logrus`, or `zerolog`, migrate to `log/slog`. It is the standard library logger since Go 1.21, has a stable API, and the ecosystem has consolidated around it. Continuing with third-party loggers means maintaining an extra dependency for no benefit.\n\n**Migration strategy:**\n\n1. Add `slog` as the new logger with `slog.SetDefault()`\n2. Bridge handlers during migration route slog output through the existing logger: [samber/slog-zap](https://github.com/samber/slog-zap), [samber/slog-logrus](https://github.com/samber/slog-logrus), [samber/slog-zerolog](https://github.com/samber/slog-zerolog)\n3. Gradually replace all `zap.L().Info(...)` / `logrus.Info(...)` / `log.Info().Msg(...)` calls with `slog.Info(...)`\n4. Once fully migrated, remove the bridge handler and the old logger dependency\n\n## Definition of Done for Observability\n\nA feature is not production-ready until it is observable. Before marking a feature as done, verify:\n\n- [ ] **Metrics declared** — counters for operations/errors, histograms for latencies, gauges for saturation. Each metric var has PromQL queries and alert rules as comments above its declaration.\n- [ ] **Logging is proper** — structured key-value pairs with `slog`, context variants used (`slog.InfoContext`), no PII in logs, errors MUST be either logged OR returned (NEVER both).\n- [ ] **Spans created","tagline":"Golang everyday observability — the always-on signals in production.
