Memory MBean

http://docs.oracle.com/javase/8/docs/api/java/lang/management/MemoryMXBean.html

The Memory MBean implements the MemoryMXBean interface, and exists as a singleton instance in the JVM. The MBean instance is accessible from the platform MBean server, either programmatically by calling ManagementFactory.getMemoryMXBean() method, or by looking up the "java.lang:type=Memory" JMX ObjectName.

The Memory MBean exposes information about the heap and the non-heap memory. Heap and non-heap memory information is returned as snapshots in the form of MemoryUsage instances.

The Memory MBean also exposes the "ObjectPendingFinalizationCount" JMX attribute, which is the approximate number for which finalization is pending.
