The following worked fine for me: 'java.lang:type=MemoryPool,name=PS Eden Space'

If you connect to your app via JConsole you will be able to see the MBeans available and the exact ObjectName of the MBean you want to use.

Got the way to do it. Used ManagementFactory.MEMORY_POOL_MXBEAN_DOMAIN_TYPE,* for defining Object name, got the instances. That solved my problem.
