BacklogDebugger
Camel supports a backlog debugger that is used for live debugging of
messages that are routed in Camel.
The backlog debugger has additional functionality for easier debugging
aimed at tooling, than the Debugger. The backlog
debugger is exposed in JMX in the tracer node with the name
BacklogDebugger
. The JMX API is defined in the
org.apache.camel.api.management.mbean.ManagedBacklogDebuggerMBean
interface.
You can enable or disable the BacklogDebugger dynamically, by calling
enableDebugger
or disableDebugger
methods.
This requires to enabled JMX by including camel-management JAR in the classpath.
