Observability Instrumentation

Implement three pillars of observability: logs, metrics, and traces.

You can't improve what you can't measure. You can't debug what you can't observe.

When to Use This Skill

Use this skill when:

• 📊 No observability: Starting from scratch
• 📝 Unstructured logs: Printf debugging, no context
• 📈 No metrics: Can't measure performance or errors
• 🐛 Hard to debug: Production issues take hours to diagnose
• 🔍 Performance unknown: No visibility into bottlenecks
• 🎯 SLO/SLA tracking: Need to measure reliability
