Correlating Traces, Logs, and Metrics
Learn to connect the three pillars of observability so you can pivot from a metric anomaly to a trace to the exact log line, dramatically speeding up distributed debugging.
Three Pillars, One Story
Observability rests on three pillars: metrics (what is wrong), traces (where it is wrong), and logs (why it is wrong). Used in isolation they are useful; correlated together they are powerful.
What Each Pillar Answers
- Metrics: aggregate trends, e.g. p99 latency rose
- Traces: the path of one request across services
- Logs: detailed events at a single point
Debugging means moving fluidly between them.
