What is @opentelemetry/instrumentation-mongodb?

@opentelemetry/instrumentation-mongodb is an npm package that provides automatic tracing for MongoDB operations using the OpenTelemetry framework. It helps in monitoring and collecting performance metrics and distributed traces for MongoDB operations, which can be useful for debugging and optimizing database interactions.

What are @opentelemetry/instrumentation-mongodb's main functionalities?

Automatic Tracing

This feature allows you to automatically trace MongoDB operations. The code sample shows how to set up the NodeTracerProvider and register the MongoDB instrumentation to start collecting traces.

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

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

registerInstrumentations({
  instrumentations: [
    new MongoDBInstrumentation(),
  ],
});

Custom Span Attributes

This feature allows you to add custom attributes to the spans created for MongoDB operations. The code sample demonstrates how to use the `responseHook` to add the MongoDB operation result as a span attribute.

const { MongoDBInstrumentation } = require('@opentelemetry/instrumentation-mongodb');

const mongoInstrumentation = new MongoDBInstrumentation({
  responseHook: (span, result) => {
    span.setAttribute('mongodb.result', JSON.stringify(result));
  },
});

Error Handling

This feature allows you to handle errors in MongoDB operations and set the span status accordingly. The code sample shows how to use the `responseHook` to check if the result is an error and set the span status.

const { MongoDBInstrumentation } = require('@opentelemetry/instrumentation-mongodb');

const mongoInstrumentation = new MongoDBInstrumentation({
  responseHook: (span, result) => {
    if (result instanceof Error) {
      span.setStatus({ code: 2, message: result.message });
    }
  },
});
