Troubleshoot JMX metrics - microsoft/ApplicationInsights-Java GitHub Wiki

This page aims to help to troubleshoot JMX metrics.

First, download JMXTerm.

After, start JMXTerm: java -jar jmxterm-1.0.2-uber.jar

Type jvms to have the PIDs of the Java applications.

The jvms command may not work (see). In this case, you can use the jcmd or jps Java command to retrieve the PID of your application before using JMXTerm.

Open a connection to your application: open <PID>.

Display the available domains: domains

Select the wanted domain: domain <domain-name>

Display the MBeans for this domain: beans

Select the wanted MBean: bean <object-name>

Display the attributes of this bean: info

You can then evaluate an attribute: get <attribute-name>

JMXTerm has added a : at the end of the objectName.

The JMX metrics configuration has to contain available objectName and attribute name.
