+
+**Notes:**
+- Metrics are collected by the API service and pushed to the configured OTLP endpoint using the OpenTelemetry Protocol over HTTP
+- The endpoint URLs must include the full path `/v1/metrics` - the OTLP exporter will not automatically append this path
+- Metrics include instance-level data (users, workspaces, projects, issues) and workspace-level data
+- When `metrics.enabled=false`, no metrics collection or export will occur
+- For self-hosted deployments pointing to your own telemetry infrastructure, update the endpoint URLs accordingly
