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.
