OpenTelemetry Bullmq Instrumentation for Node.js

Node.js CI npm version

This module provides automatic tracing instrumentation for BullMQ.

Compatible with OpenTelemetry JS API and SDK 1.0+.

Installation

npm install --save @jenniferplusplus/opentelemetry-instrumentation-bullmq

Supported Versions

  • [1.90.1, 2.x, 3.x, 4.x, 5.x]

It's likely that the instrumentation would support earlier versions of BullMQ, but I haven't tested it.

Usage

OpenTelemetry Bullmq Instrumentation allows the user to automatically collect trace data from Bullmq jobs and workers and export them to the backend of choice.

To load the instrumentation, specify it in the instrumentations list to registerInstrumentations. There is currently no configuration option.

const { NodeTracerProvider } = require('@opentelemetry/sdk-trace-node');
const { registerInstrumentations } = require('@opentelemetry/instrumentation');
const { BullMQInstrumentation } = require('@jenniferplusplus/opentelemetry-instrumentation-bullmq');

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

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

Contributing

I no longer use BullMQ in any of my projects, and so I have no cause to update this library. I will continue to update to support new versions of node.js, and backward-compatible versions of BullMQ. I'm not accepting new features, and I would likely not make updates for any breaking changes in BullMQ. I plan to deprecate this package when there is a clear successor. Currently, AppSignals's implementation is the most mature. The API and emitted telemetry is very similar to this one as it was forked from this project. Taskforce.sh is also developing a first-party tracing solution.
