When the FederationComponent is initially created, the ManagementCacheListener afterCreate method is invoked. This causes a proxy representation of the MBean to be registered in the MBeanServer using MBeanJMXAdapter registerMBeanProxy.
Some examples are:
GemFire:service=CacheService,name=LuceneService,type=Member,member=192.168.2.13(69570)<ec><v1>-1025
GemFire:type=Member,member=192.168.2.13(69570)<ec><v1>-1025
GemFire:service=LockService,name=gatewayEventIdIndexMetaData_lockService,type=Member,member=192.168.2.13(69570)<ec><v1>-1025
GemFire:service=DiskStore,name=DEFAULT,type=Member,member=192.168.2.13(69570)<ec><v1>-1025
GemFire:service=CacheServer,port=58176,type=Member,member=192.168.2.13(69570)<ec><v1>-1025
GemFire:service=AsyncEventQueue,queue=full_index#_data,type=Member,member=192.168.2.13(69570)<ec><v1>-1025
GemFire:service=Region,name=/data,type=Member,member=192.168.2.13(69570)<ec><v1>-1025
Aggregation
Depending on the MBean, an AggregateHandler is invoked to aggregate the data.
When the ManagementCacheListener afterUpdate method is invoked, it retrieves the proxy and updates the state of the MBean.
More details to come.
MBean State Retrieval
What is registered for each ObjectName by the registerMBeanProxy method is a MBeanProxyInvocationHandler. This object handles requests from JMX clients. MBean state is retrieved in one of two ways, either by operation or by attribute.
All operations are forwarded to the appropriate member using the MBeanProxyInvocationHandler delegateToFunctionService method. This method executes the ManagementFunction in the member. The ManagementFunction uses the local MBeanServer to invoke the operation on the MBean represented by the ObjectName.
What is registered for each MBean by the registerMBeanProxy method is a MBeanProxyInvocationHandler. This object handles requests from JMX clients. When a request is received, it is handled in one of two ways. All requests for attributes are handled by the MBeanProxyInvocationHandler delegateToObjectState method. This method gets the FederationComponent from the local monitoring region and retrieves the value of the requested attribute. All requests for operations are handled by the MBeanProxyInvocationHandler delegateToFunctionService method. This method executes the ManagementFunction to forward the operation to the appropriate member. The ManagementFunction executes in the member and uses the MBeanServer to invoke the operation on the MBean.

All attributes are retrieved in the JMX manager using the MBeanProxyInvocationHandler delegateToObjectState method. This method gets the FederationComponent from the local monitoring region and retrieves value of the requested attribute.
