Grafana dashboard 09_grpc_server.jsonnet

gRPC Server

Call-level gRPC server traffic, status distribution, latency, and failures for generated RPC endpoints.

When to use

Use this page to understand the generated dashboard, its panels, and the signals behind them.

Behavior

The code generator creates Jsonnet sources for every generated service. make grafana-dashboards renders them to Grafana JSON.

Call-level scope

The canonical dashboard focuses on complete calls. Current OpenTelemetry gRPC instrumentation does not expose the former per-message metric family, so message-level panels are intentionally not generated.
