[Shoryuken](https://github.com/phstc/shoryuken) is a thread-based message processor for [AWS SQS][aws-sqs].

AppSignal instruments Shoryuken automatically when the Shoryuken gem is detected on start. No manual installation is required if Shoryuken is part of a Rails app. If you're using a standalone Shoryuken app, see our [integration guide][integration-guide].

## Performance monitoring

### Event timeline

Shoryuken jobs appear in the event timeline of your application's performance actions as `perform_job.shoryuken` events.

### Incident grouping

AppSignal detects job names from the Shoryuken 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 Shoryuken job records an `enqueue.shoryuken` 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.

## Batch support

If an app uses a worker with the `:batch => true` option, that worker processes multiple messages in the same tick. This requires Ruby gem `2.11.3` or higher, which adds support for the batch option.

<CodeGroup>
  ```ruby Ruby theme={null}
  # my_worker.rb
  class MyWorker
    include Shoryuken::Worker

    shoryuken_options :queue => "batched", :batch => true

    def perform(sqs_msg, body)
      # Do stuff
      puts "Performing BatchedWorker job: #{body}"
      sleep 1
    end
  end
  ```
</CodeGroup>

## Example application

We have an example application for a standalone Shoryuken application available in our [examples repository][example-app] on GitHub.
