OpenTelemetry gRPC Instrumentation for Node.js

Note: This is an experimental package under active development. New releases may include breaking changes.

This module provides automatic instrumentation for @grpc/grpc-js. Currently, version 1.x of @grpc/grpc-js is supported.

For automatic instrumentation see the @opentelemetry/sdk-trace-node package.

Installation

npm install --save @opentelemetry/instrumentation-grpc

Supported Versions

• @grpc/grpc-js versions ^1.0.0

Usage

OpenTelemetry gRPC Instrumentation allows the user to automatically collect trace data and export them to the backend of choice, to give observability to distributed systems when working with (grpc-js).

To load a specific instrumentation (gRPC in this case), specify it in the Node Tracer's configuration.

const { NodeTracerProvider } = require('@opentelemetry/sdk-trace-node');
const { GrpcInstrumentation } = require('@opentelemetry/instrumentation-grpc');
const { registerInstrumentations } = require('@opentelemetry/instrumentation');

const provider = new NodeTracerProvider();

provider.addSpanProcessor(new SimpleSpanProcessor(new ConsoleSpanExporter()));
provider.register();

registerInstrumentations({
  instrumentations: [new GrpcInstrumentation()]
});

See examples/grpc-js for examples.
