The Three Pillars: Logs, Metrics, and Traces Explained

• What Are the Three Pillars?

  Modern observability rests on three key data sources: logs, metrics, and traces.Logs capture detailed records of events—what happened, when, and sometimes why.Metrics summarize system health and performance in numbers—like latency, error rates, or CPU usage.Traces follow requests as they travel through distributed systems, mapping their path and highlighting where things slow down or fail.

• Why You Need All Three

  No single pillar gives the full picture.Metrics can signal that something’s wrong, logs provide the details, and traces show how requests flow across services.Teams that unify all three can spot subtle issues, rapidly diagnose incidents, and understand system behavior at every layer.

• The Pillars in Action

  Imagine troubleshooting a slow user experience: metrics flag higher response times, logs reveal an error in a backend service, and traces pinpoint exactly where in the chain the delay occurs.Organizations embracing all three pillars report up to 40% faster incident resolution and more reliable, user-friendly systems.

Is your team making the most of logs, metrics, and traces?
