Re-explain

The three pillars of observability are:

  1. Metrics: Quantitative data about system performance (CPU usage, response time, error rates)
  2. Logs: Discrete events that happened in the system with context and details
  3. Traces: Records of requests as they flow through multiple services in distributed systems
    These pillars work together to provide comprehensive visibility:
  • Metrics show you WHAT is happening
  • Logs tell you WHY it's happening
  • Traces show you WHERE it's happening across services
