Tracing WS (Websocket) consumers can be done in two methods:

1. Auto-tracing using the environment variable.
2. Calling the SDK.
   Calling the SDK is simple, and should be done in your main js file where the consumer is being initialized:

const epsagon = require('epsagon-frameworks');
epsagon.init({
  token: 'epsagon-token',
  appName: 'app-name-stage',
  metadataOnly: false,
});

Tagging traces or setting custom errors can be by:

socket.on('message', (message) => {
    message.epsagon.label('key', 'value');
    message.epsagon.setError(Error('My custom error'));
})
