JMX (Java Management Extension) allows to monitor statistics about asynchronnous messages or starts administration operations.
JVM and Camel attributes
See Camel JMX for more info about Camel attributes and operations - "By default, JMX instrumentation agent is enabled in Camel, which means that Camel runtime creates and registers MBean management objects with a MBeanServer instance in the VM. This allows Camel users to instantly obtain insights into how Camel routes perform down to the individual processor level. The supported types of management objects are endpoint, route, service, and processor."
Parameter | Description | Note |
Current heap size | Current heap memory size. | If there is no enough memory then garbage collector needs more often to free memory and the performance is suffering. |
Maximum heap size | Maximum heap memory size. | Related to the previous parameter. |
Live threads | Current count of running threads | If there is trend with increasing number of threads then it seems to be a problem. |
