## Observability & diagnostics

QuestDB provides real-time metrics, a health check endpoint, and logging to monitor performance and simplify troubleshooting.

- **Metrics:**
  QuestDB exposes detailed [metrics in Prometheus format](/docs/operations/logging-metrics/#metrics), including query
  statistics, memory usage, and I/O details.

- **Health check:**
  A [minimal HTTP server](/docs/operations/logging-metrics/#minimal-http-server) monitors system health.

- **Metadata tables:**
  The engine provides [metadata tables](/docs/query/functions/meta/) to query
   table status, partition status, query execution, and latency.

- **Extensive logging:**
  [Logging](/docs/operations/logging-metrics/) covers SQL parsing, execution, background processing, and runtime exceptions. The framework minimizes performance impact.

- **Real-time metric dashboards:**
  The web console lets you create dashboards that display per-table metrics.
