VerboseGC demonstrates the use of the java.lang.management API to
print the garbage collection statistics and memory usage remotely
by connecting to a JMX agent with a JMX service URL:
service:jmx:rmi:///jndi/rmi://<hostName>:<portNum>/jmxrmi
where <hostName> is the hostname and <portNum> is the port number
to which the JMX agent will be connected.
To run the VerboseGC demo
(1) Start the application with the JMX agent - here's an example of
how the Java2D is started
java -Dcom.sun.management.jmxremote.port=1090
-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.authenticate=false
-jar <JDK_HOME>/demo/jfc/Java2D/Java2Demo.jar
This instruction uses the Sun's built-in support to enable a JMX agent.
You can programmatically start a JMX agent with the RMI connector
using javax.management.remote API. See the javadoc and examples for
javax.management.remote API for details.
(2) Run VerboseGC
java -jar <JDK_HOME>/demo/management/VerboseGC/VerboseGC.jar localhost:1090
These instructions assume that this installation's version of the java
command is in your path. If it isn't, then you should either
specify the complete path to the java command or update your
PATH environment variable as described in the installation
instructions for the Java(TM) SDK.
