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.
