The Grafbase Enterprise Platform control plane emits OpenTelemetry metrics. This is configured through the standard OpenTelemetry environment variables, in particular OTEL_EXPORTER_OTLP_ENDPOINT and OTEL_SERVICE_NAME.
This mechanism is in place starting with version 0.6.5 of the api and telemetry-sink docker images.
The API and the HTTP listener of the telemetry sink both expose the HTTP metrics defined in OTEL semantic conventions.
The gRPC listener of the telemetry sink exposes the following metrics:
| Metric Name | Type | Description | Labels |
|---|---|---|---|
grpc_server_started | Counter | Total number of RPCs started on the server | grpc_service, grpc_method |
grpc_server_handled | Counter | Total number of RPCs completed on the server | grpc_service, grpc_method, grpc_code |
grpc_server_handling_duration_seconds | Histogram | RPC call duration in seconds | grpc_service, grpc_method, grpc_code |
grpc_server_active_requests | UpDownCounter | Current number of active server requests | grpc_service, grpc_method |
Request duration is tracked with the following bucket boundaries (in seconds): 0.001, 0.005, 0.01, 0.015, 0.020, 0.025, 0.50, 0.75, 1.0, 2.0
grpc_service: The gRPC service name (extracted from request path).grpc_method: The gRPC method name (extracted from request path).grpc_code: The gRPC response status code (e.g.,Ok,Unknown, etc.) - only on completed requests.
