Hi I have tomcat and ganglia-gmond installed on a server.
I would like to monitor tomcat but receive a number of errors when trying
to run from the command line. I followed the instructions here.
https://github.com/ganglia/jmxetric
I'm not sure what I'm missing. jmxetric-1.0.8.jar is in the directory I'm
executing from.
I have not setup any environment variables besides general tomcat catalina
variables.
Thanks!
command line:
=========================================================
java
-javaagent:jmxetric-1.0.8.jar=host="localhost",port="8649",config="jmxetric-master/etc/jmxetric.xml",
wireformat31x=true, mode="unicast"
errors after execution:
