Observability (Metrics, Logging, Tracing)

Observability refers to the ability to understand the internal state and behavior of a system based on the data it generates, typically through metrics, logs, and traces. For a streaming system like RisingWave, observability is crucial for monitoring performance, diagnosing issues, understanding data flow, and managing cluster resources effectively. RisingWave exposes various metrics and logs to support observability tooling.
