The Pillars: Logs, Metrics, Traces
Explore the three distinct but complementary signals of observability: logs, metrics, and traces. Understand their individual strengths and how they work together.
Observability's Core Pillars
Observability rests on three pillars: logs, metrics, and traces. Each gives a different view, and together they paint a full picture of your system.
Logs: The Event Diary
Logs are your system's diary — text records of discrete events like a login or an error. They tell you exactly what happened and when.
