Interface JVMMemoryStats

All Superinterfaces:

javax.management.j2ee.statistics.Stats

public interface JVMMemoryStats
extends javax.management.j2ee.statistics.Stats

A Stats interface, to expose the monitoring information about the JVM memory subsystem. This interfaces exposes the memory usage information for the heap and the non-heap areas of the memory subsystem.

Since:

8.1
