SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Go projects often struggle with high-volume, structured logging that is easy to route, filter, and back-end efficiently. This skill shows how to compose pipelines using samber/slog libraries to achieve deterministic performance and clear log structures.

Core Features & Use Cases

  • 20+ composable slog.Handler packages for Go 1.21+ that enable pipeline construction, routing, and sinks.
  • Deterministic pipeline ordering (sampling outermost, then formatting, then routing) to minimize wasted CPU and ensure sinks see clean data.
  • HTTP middlewares and backends integration with versioned modules (e.g. slog-datadog, slog-loki, slog-sentry) for production-grade deployments.
  • Practical guidance for using Router vs Fanout, first-match vs multi-predicate routing, and graceful shutdown for batched sinks.

Quick Start

Configure a pipeline that samples noisy logs, formats attributes to remove sensitive data, and routes errors to Sentry while streaming normal logs to Loki.

FAQPage Schema
How do I configure structured logging pipelines in Go for high-throughput services?

Configure structured logging pipelines in Go using samber/slog libraries to produce scalable, policy-compliant logs. It demonstrates proper pipeline ordering with sampling outermost, correct use of Router vs Fanout, and graceful shutdown of batched sinks using Option{}.NewXxxHandler constructors.

What's the best way to route Go slog logs to multiple backends like Sentry and Loki?

Route Go slog logs to multiple backends like Sentry and Loki using the Router and Fanout components. Router handles first-match routing for specific conditions, while Fanout supports multi-predicate routing to send logs to multiple destinations simultaneously.

How do I add log sampling and filtering middleware in Go slog pipelines?

Add log sampling and filtering middleware in Go slog by composing 20+ slog.Handler packages. Ensure deterministic pipeline ordering by placing sampling outermost, then formatting, then routing to minimize wasted CPU and ensure sinks see clean data.

Does the samber/slog pipeline support graceful shutdown for batched log sinks?

Yes, samber/slog pipelines support graceful shutdown for batched log sinks. The Skill demonstrates using the Option{}.NewXxxHandler constructors to properly configure and flush batched sinks during service shutdown.

When do I use Router vs Fanout for structured logging in Go services?

Use Router for first-match routing when you need logs to go to a single destination based on predicates. Use Fanout for multi-predicate routing when logs must be sent to multiple destinations simultaneously across your structured logging pipeline.

Can I integrate HTTP middleware with Go slog pipelines for production logging?

Yes, you can integrate HTTP middleware with Go slog pipelines. The Skill provides HTTP middlewares and backend integration with versioned modules like slog-datadog, slog-loki, and slog-sentry for production-grade deployments.
