[Resque](https://github.com/resque/resque) is a Redis-backed Ruby library for creating background jobs, placing them on multiple queues, and processing them later.

AppSignal instruments Resque automatically when the Resque gem is detected on start. No manual setup is required.

## Performance monitoring

### Event timeline

Resque jobs appear in the event timeline of your application's performance actions as `perform.resque` events.

### Incident grouping

AppSignal detects job names from the Resque worker class name, suffixed with the `perform` method name, resulting in something like `MyWorker#perform`. AppSignal groups jobs by this name for performance incidents and notifications.

## Enqueue instrumentation

<Compatibility
  versions={[
{ name: "AppSignal for Ruby", version: "4.9.0" }
]}
/>

Enqueuing a Resque job records an `enqueue.resque` event, titled after the job being enqueued.

AppSignal records enqueue events on the active transaction's event timeline, for example when you enqueue a job from within a web request or from within another job. It only records them when a transaction is active, so enqueuing a job outside of a transaction records nothing.

To stop recording enqueue events across all background job integrations, set the [`enable_job_enqueue_instrumentation` config option](/ruby/configuration/options#option-enable_job_enqueue_instrumentation) to `false`. This does not affect the instrumentation of the jobs themselves.

## Active Job support

The Resque integration is compatible with [Active Job](/ruby/integrations/active-job).

Upgrade to version 2.11.0 of the Ruby gem or newer for improved support.

## Example apps

We've added a Rails 5 + Resque [example app](https://github.com/appsignal/appsignal-examples/tree/rails-5+resque) to our [examples repository](https://github.com/appsignal/appsignal-examples). Take a look if you're having trouble getting AppSignal for Resque configured.
