JMXCLIENT

This is a simple utility to work with JMX from command line interface.

Requirements:

• jshell from jdk is required.
• management agent have to be started. Can be started on running JVM with jcmd PID ManagementAgent.start_local

Usage:

• jshell -R-Dpid=PID -R-Dcommand=getBeans jmxclient.jsh
• jshell -R-Dpid=PID -R-Dcommand=getBeanInfo -R-Dbean=java.lang:type=Memory jmxclient.jsh
• jshell -R-Dpid=PID -R-Dcommand=getAttribute -R-Dbean=java.lang:type=Memory -R-Dmethod=HeapMemoryUsage jmxclient.jsh
• jshell -R-Dpid=PID -R-Dcommand=invoke -R-Dbean=java.lang:type=Memory -R-Dmethod=gc jmxclient.jsh
• jshell -R-Dpid=PID -R-Dcommand=dumpBeans jmxclient.jsh
• jshell -R-Dpid=PID -R-Dcommand=dumpBeans -R-Dbean=java.lang:* jmxclient.jsh
• jshell -R-Dpid=PID -R-Dcommand=dumpBeansAsJson jmxclient.jsh
• jshell -R-Dpid=PID -R-Dcommand=dumpBeansAsJson -R-Dbean=java.lang:* jmxclient.jsh

Available options:

• -R-Dpid=PID - java process id you want attach to
• -R-Dcommand=help|getBeans|getBeanInfo|getAttribute|invoke|dumpBeans|dumpBeansAsJson - specify what to do
• -R-Dbean=BEAN_PATH - full path to mbean object like: java.lang:type=Memory, supports wildcards for dumpBeans and dumpBeansAsJson
• -R-Dmethod=METHOD_NAME - attribute or operation name
• -R-Dargs=ARGUMENTS - additional method arguments separated by space

Commands:

• help - show help
• getBeans - output a list of all available MBeans
• getBeanInfo - output all available attributes and operations for MBean
• getAttribute - output MBean attribute value
• invoke - run MBean operation
• dumpBeans - dump all MBean attribute values as a flat list in beanName.attribute = value format; optionally scoped to a wildcard bean pattern
• dumpBeansAsJson - dump all MBean attribute values as JSON; optionally scoped to a wildcard bean pattern
