I am trying to monitor a tomcat application using percona cacti graphs. The application works using jconsole from windows. The host is centos 6.6 64 bit and i have installed ant.
When i try to run the example given by percona it does not work for me.
[root@titan ~]# ant -Djmx.server.port=12345 -e -q -f jmx-monitor.xml -v

I have noticed I had to remove the following from the jmx-monitor.xml to get it to work.
<jmx:get
name="Catalina:type=ThreadPool,name=${jmx.catalina.threadpool.name}"
attribute="currentThreadsBusy"
resultproperty="currentThreadsBusy"
/>
<jmx:get
name="Catalina:type=ThreadPool,name=${jmx.catalina.threadpool.name}"
attribute="currentThreadCount"
resultproperty="currentThreadCount"
/>
<jmx:get
name="Catalina:type=ThreadPool,name=${jmx.catalina.threadpool.name}"
attribute="maxThreads"
resultproperty="maxThreads"
/>
current_threads_busy: ${currentThreadsBusy}
current_thread_count: ${currentThreadCount}
max_threads: ${maxThreads}
How would i get it to work without remove the above. The following command is run by cati
ant -Djmx.server.port=9012 -Djmx.catalina.threadpool.name=http-8080 -e -q -f jmx-monitor.xml
According your work, I just added the following line to jmx-monitor.xml.
<property name="jmx.catalina.threadpool.name" value="http-8080" />
And it works.
ant -Djmx.server.port=12345 -e -q -f jmx-monitor.xml -v
or Just test by the following command. (I think that docs is not good in http://www.percona.com/doc/percona-monitoring-plugins/1.1/cacti/jmx-templates.html)
ant -Djmx.server.port=9012 -e -q -f jmx-monitor.xml -Djmx.catalina.threadpool.name=http-8080
