The Control Bus from the EIP patterns allows for the integration system to be monitored and managed from within the framework.
Use a Control Bus to manage an enterprise integration system. The Control Bus uses the same messaging mechanism used by the application data, but uses separate channels to transmit data that is relevant to the management of components involved in the message flow. In Camel you can manage and monitor using JMX, or by using a Java API from the CamelContext, or from the org.apache.camel.api.management package, or use the event notifier (example on the Camel site). Starting with Camel 2.11 a new ControlBus Component will be available that allows you to send messages to a control bus Endpoint that will react accordingly.
