Check JVM status with JMX

[jnunez47]

Hi friends, I have a doubt with Zabbix and JMX monitoring because I need to monitoring a java application.

I followed the instructions of this link: https://www.zabbix.com/documentation...jmx_monitoring

I have Zabbix Server with Zabbix Java Gateway in a VPS and the java application in other server (VPS).

To test, I created an iteam with the key: jmx["java.lang:type=Memory","HeapMemoryUsage.used"] but I don't see anything in the item's graph.

When I try to test this item on client and I receive this response:

ubuntu@wrapper-lab:/usr/bin$ zabbix_agent -t jmx["java.lang:type=Memory","HeapMemoryUsage.used"]
jmx[java.lang:type=Memory,HeapMemoryUsage.used] [m|ZBX_NOTSUPPORTED]

What am I doing wrong?

You probably just have an error in the key.

To get the full list of jmx keys for your jvm, try running JConsole while your java app is up. Put whatever strings you find there inside jmx["here"] and it ought to be good.

I made a test with JConsole in my PC, and I can watch the monitor correctly, but zabbix agent doesn't found. I have linking "JMX Generic" template in my host.

This is my command line to execute my java application:

java -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=10052 -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -Xms512M -Xmx1024M -d64 -jar jasolina.jar

zabbix_agent -t jmx["java.lang:type=Memory","HeapMemoryUsage.used"]
jmx[java.lang:type=Memory,HeapMemoryUsage.used] [m|ZBX_NOTSUPPORTED]
