golang-samber-slog
golang samber slog
What it does
- github.com/samber/slog-multi — handler composition
- github.com/samber/slog-sampling — throughput control
- github.com/samber/slog-formatter — attribute transformation
- Fanout latency = sum of all handler latencies (sequential). With 5 handlers at 10ms each, every log call costs 50ms. Use Pool() to reduce to max(latencies)
- Pipe middleware adds per-record function call overhead — keep chains short (2-4 middlewares)
- Benchmark your pipeline with go test -bench before production deployment
- → See samber/cc-skills-golang@golang-observability skill for slog fundamentals (levels, context, handler setup, migration)
Requirements & configuration
- Six composition patterns, each for a different routing need:
- 5. Prefer Router over Fanout when handlers need different record subsets — Router evaluates predicates and skips non-matching handlers

golang-samber-slog FAQ
What does the golang-samber-slog skill do?
Structured logging extensions for Golang using samber/slog-**** packages — multi-handler pipelines (slog-multi), log sampling (slog-sampling), attribute formatting (slog-formatter), HTTP middleware (slog-fiber, slog-gin, slog-chi, slog-echo), and backend routing (slog-datadog, slog-sentry, slog-loki, slog-syslog, slog-logstash, slog-graylog...). Apply when using or adopting slog, or when the codebase already imports any github.com/samber/slog-* package. github.com/samber/slog-multi — handler composition github.com/samber/slog-sampling — throughput control
