-  mod_cluster/1.2.8.Final: This denotes the version of the mod_cluster native library
-  ajp://192.168.122.204:8099: This denotes the protocol used (either one of AJP, HTTP, HTTPS), hostname or IP address of the worker node and the port
-  jboss-eap-6.3-2: This denotes the worker node's JVMRoute.
-  Virtual Host 1: This denotes the virtual host(s) configured on the worker node
sticky-session-forceis set to "true"
-  Load balancing group (LBGroup): The
load-balancing-groupproperty is set in the mod_cluster subsystem in EAP configuration to group all worker nodes into custom load balancing groups. Load balancing group (LBGroup) is an informational field which gives information about all set load balancing groups. If this field is not set, then all worker nodes are grouped into a single default load balancing group
NoteThis is only an informational field and thus cannot be used to set
load-balancing-groupproperty. The property has to be set in mod_cluster subsystem in EAP configuration.
-  Load (value): This indicates the load factor on the worker node. The load factor(s) are evaluated as below:
-load > 0: A load factor with value 1 indicates that the worker node is overloaded. A load factor of 100 denotes a free and not-loaded node.
-load = 0:A load factor of value 0 indicates that the worker node is in a standby mode. This means that no session requests will be routed to this node until and unless the other worker nodes are unavailable
-load = -1: A load factor of value -1 indicates that the worker node is in an error state.
-load = -2: A load factor of value -2 indicates that the worker node is undergoing CPing/CPong and is in a transition state
