monitoring-patterns

Production observability patterns — structured logging (Pino, Winston, zerolog with correlation IDs and redaction), Prometheus metrics (RED/USE methods, prom-client, client_golang, custom business metrics, label best practices), alerting rules (Prometheus rules, Alertmanager routing, SLO burn-rate alerts, severity levels, alert fatigue prevention), health checks (liveness/readiness/startup probes, dependency checkers, Kubernetes configuration, graceful degradation), distributed tracing (OpenTelemetry SDK for Node.js and Go, auto-instrumentation, manual spans, context propagation, sampling strategies, collector config), and Grafana dashboards (PromQL queries, RED/USE/SLO/database dashboards, JSON provisioning, variables, GitOps). 6 skills, 3 commands, 1 agent.
