Action Cable

This feature requires AppSignal for Ruby version 2.3.0 or higher.

Action Cable is Rails' framework for WebSocket connections, allowing real-time communication between the server and client.

Supported instrumentation

When you have Action Cable channels in your Rails application, AppSignal automatically tracks:

  • Channel subscription events
  • Channel messages
  • Error tracking in channels

All Action Cable activity is reported under your application's "action_cable" namespace.

No additional configuration needed

AppSignal supports Action Cable out-of-the-box without the need for manual instrumentation.

For additional Rails setup instructions, see our Rails integration guide.
