How to use JMX/tomcat User parameters in agent file.

[sunnysthakur]

Hello,

We were using Nagios for Server Monitoring and now switching to Zabbix due to its good front end.

I am facing a challenge to monitor Tomcat monitoring via zabbix now.

Below are the steps i performed for tomcat monitoring.


1. Added the below line in catalina.sh to enable jmx

JAVA_OPTS="$JAVA_OPTS -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=9001 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false"

2. After above step i am able to view the output from tomcat server once i am executing the below command on Zabbix server.

[root@monitor ~]# java -jar cmdline-jmxclient-0.10.3.jar '-':'-' [B]10.0.0.234:9001 java.lang:type=OperatingSystem ProcessCpuTime
01/19/2013 13:34:58 +0530 org.archive.jmx.Client ProcessCpuTime: 10040000000[/B]

3. Now i setup the above command in agent file of tomcat server

UserParameter=jvm.maxthreads, java -jar /root/cmdline-jmxclient-0.10.3.jar '-':'-' 10.0.0.234:9001 java.lang:type=Threading PeakThreadCount

UserParameter=jvm.maxthreads, java -jar /root/cmdline-jmxclient-0.10.3.jar '-':'-' 10.0.0.234:9001 java.lang:type=OperatingSystem ProcessCpuTime

4. I also attached the tomcat template on added tomcat server in zabbix front end.

After performing all the above steps i am not able to view the tomcat data on zabbix server.

Please help me on this if i am missing something in above setup.

Did you restart the agent daemon after adding your new user parameter? That's a required step when adding custom checks.

Also, what version of Zabbix are you using? The 2.0.x series supports JMX monitoring out-of-the-box, so there isn't a need to set up custom Agent checks for JMX stuff (assuming the Zabbix server can hit the JMX interface). To get that all working, just do the following steps:

1. Set up the Zabbix Java Gateway by following the instructions in the Zabbix documentation.
2. Follow the instructions at the Zabbix JMX documentation to get your JMX monitoring working.

Hello heaje,

I am using Zabbix Server 1.8.2 and agent version 1.8.2 and setup server-agent for active checks.

After added these jmx user parameters i restarted the server but didn't reflect the changes on server.

You means to say in version 2.0 supports tomcat/jmx monitoring without adding these parameters to agent ?

And 2.0 is supporting on Red hat/CentOS 6 version and i am using CentoS 5.8

And one more thing i am not able to alter the output generated by

java -jar cmdline-jmxclient-0.10.3.jar '-':'-' 10.0.0.234:9001 java.lang:type=OperatingSystem ProcessCpuTime

01/21/2013 07:24:39 +0530 org.archive.jmx.Client ProcessCpuTime: 98160000000

I am not able to see the result of tomcat on zabbix dashboard

Please help on this
