BullMQ is a Node.js job queue library backed by Redis. The AppSignal for Node.js integration for BullMQ instruments the enqueueing and processing in your application.

​
Installation

The BullMQ package is instrumented automatically by the AppSignal for Node.js package. If you run your workers as separate processes, make sure to also use node --require appsignal.cjs ... when starting the worker processes, so that AppSignal can instrument the workers’ job processing.

​
Features

When using the BullMQ integration, AppSignal will create a performance sample for each job that is processed by a worker. When a job is enqueued in an instrumented context, such as a web request or background job, AppSignal will display an event in the performance sample’s event timeline representing the job enqueueing.
