You can prefix the JMX instance in the connection block for each
application using the "InstancePrefix" attribute. Here is an example from
one of my hosts where I'm monitoring activemq and cassandra on the same
host. All cassandra metrics will have a CAS- in front of them, and all
activemq metrics will be prefixed with AMQ-
#######################
# Connection block(s) #
#######################
<Connection>
Host "myhost"
InstancePrefix "CAS-"
ServiceURL "service:jmx:rmi:///jndi/rmi://localhost:7199/jmxrmi"
Collect "memory_pool"
Collect "memory-heap"
Collect "memory_nonheap"
Collect "java_threads"
Collect "classes"
Collect "garbage_collector"
Collect "jvm_uptime"
</Connection>
<Connection>
Host "myhost"
InstancePrefix "AMQ-"
ServiceURL "service:jmx:rmi:///jndi/rmi://localhost:1099/jmxrmi"
Collect "memory_pool"
Collect "memory-heap"
Collect "memory_nonheap"
Collect "java_threads"
Collect "classes"
Collect "garbage_collector"
Collect "jvm_uptime"
</Connection>
Hope this helps!
