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
    }),
  ],
});

Mongo instrumentation Options

Mongodb instrumentation has few options available to choose from. You can set the following:

Options	Type	Description
`enhancedDatabaseReporting`	`string`	If true, additional information about query parameters and results will be attached (as `attributes`) to spans representing database operations
`responseHook`	`MongoDBInstrumentationExecutionResponseHook` (function)	Function for adding custom attributes from db response
