PostHog logs for Go
PostHog logs for Other Languages
Implement structured logging with JSON formats, log levels (DEBUG, INFO, WARN, ERROR), contextual logging, PII handling, and centralized logging. Use for logging, observability, log levels, structured logs, or debugging.
Monitoring and observability with OpenTelemetry, Prometheus, Grafana dashboards, and structured logging
xUnit 測試輸出與記錄完整指南。當需要在 xUnit 測試中實作測試輸出、診斷記錄或 ILogger 替代品時使用。涵蓋 ITestOutputHelper 注入、AbstractLogger 模式、結構化輸出設計。包含 XUnitLogger、CompositeLogger、效能測試診斷工具實作。 Keywords: ITestOutputHelper, ILogger testing, test output xunit, 測試輸出, 測試記錄, AbstractLogger, XUnitLogger, CompositeLogger, testOutputHelper.WriteLine, 測試診斷, logger mock, 測試日誌, 結構化輸出, Received().Log
Monitoring, logging, and tracing implementation using OpenTelemetry as the unified standard. Use when building production systems requiring visibility into performance, errors, and behavior. Covers OpenTelemetry (metrics, logs, traces), Prometheus, Grafana, Loki, Jaeger, Tempo, structured logging (structlog, tracing, slog, pino), and alerting.
Implements OpenTelemetry (OTEL) logging with trace context correlation and structured logging. Use when setting up production logging with OTEL exporters, structlog/loguru integration, trace context propagation, and comprehensive test patterns. Covers Python implementations for FastAPI, Kafka consumers, and background jobs. Includes OTLP, Jaeger, and console exporters.
Production observability with structured logging, metrics collection, distributed tracing, and alerting
Use this skill when writing or reviewing C# code to follow project conventions. Covers naming standards, async patterns, CancellationToken usage, structured logging, nullable reference types, and formatting rules. Apply when authoring new C# classes, reviewing code style, or ensuring consistency with existing patterns.
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.
Golang everyday observability — the always-on signals in production. Covers structured logging with slog, Prometheus metrics, OpenTelemetry distributed tracing, continuous profiling with pprof/Pyroscope, server-side RUM event tracking, alerting, and Grafana dashboards. Apply when instrumenting Go services for production monitoring, setting up metrics or alerting, adding OpenTelemetry tracing, correlating logs with traces, migrating legacy loggers (zap/logrus/zerolog) to slog, adding observability to new features, or implementing GDPR/CCPA-compliant tracking with Customer Data Platforms (CDP). Not for temporary deep-dive performance investigation (→ See golang-benchmark and golang-performance skills).
Add PostHog log capture to track application logs. Use after implementing features or reviewing PRs to ensure meaningful log events are captured with structured properties. Also handles initial OTLP exporter setup if not yet configured.
