@opentelemetry/instrumentation-mongodb

OpenTelemetry MongoDB Instrumentation for Node.js

This module provides automatic instrumentation for the mongodb module, which may be loaded using the @opentelemetry/sdk-trace-node package and is included in the @opentelemetry/auto-instrumentations-node bundle.

If total installation size is not constrained, it is recommended to use the @opentelemetry/auto-instrumentations-node bundle with @opentelemetry/sdk-node for the most seamless instrumentation experience.

Compatible with OpenTelemetry JS API and SDK 1.0+.

Installation

npm install --save @opentelemetry/instrumentation-mongodb

Supported Versions

• >=3.3 <7

Usage

OpenTelemetry MongoDB Instrumentation allows the user to automatically collect trace data and export them to their backend of choice, to give observability to distributed systems.

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

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

const provider = new NodeTracerProvider();
provider.register();

registerInstrumentations({
  instrumentations: [
    new MongoDBInstrumentation({
      // see under for available configuration
    }),
  ],
});

See examples/mongodb for a short example.
