An external receiver can be configured to listen on the com.apama.input channel, which is a wildcard channel for all events that come into the correlator. This can be useful for diagnostics, testing, or auditing, but it is not recommended for production. In a production environment, the recommendation is to explicitly specify the channels that the receiver should listen on.

A monitor instance cannot subscribe to com.apama.input.

To configure an external receiver to process all events generated in the correlator, specify that the receiver listens on the default channel (""). With this specification, a receiver would get all events generated by the send...to channel and emit statements regardless of the channel the event was directed to. Events generated by the enqueue or route statements are not delivered to the default channel.
