agent monitoring with ganglia

[Ge Zhu]

Hi,I set up a ganglia(3.6) server to  monitor the flume agent with the 
flume-env.sh configured as below:JAVA_OPTS="-Xms500m -Xmx500m 
-Dcom.sun.management.jmxremote -Dflume.monitoring.type=ganglia 
-Dflume.monitoring.hosts=xxx.xxx.xxx.xxx:8649.
however, after i start the flume agent, there is no graph for flume metrics 
show in the ganglia ui. Do i need to install the gmond in the machine that 
running flume agent? or is there any configuration  i need to do?
Cheers
