Observability in YDB SDK

This section describes how to enable YDB SDK diagnostic tools — logging, metrics, and distributed tracing. It is recommended to enable them in advance, before problems occur, so that when investigating an incident you can see the full picture of the system state before, during, and after the failure.

Logging:

• Enabling logging
• Exporting logs to OpenTelemetry

Metrics:

• Metrics with OpenTelemetry
• Enabling metrics in Prometheus

Tracing:

• Tracing with OpenTelemetry
• Enabling tracing in Jaeger

Server-side observability YDB, which is independent of the SDK, is described in the Reference on YDB observability section.
