Interface JVMMemoryStats

All Superinterfaces:

Stats

public interface JVMMemoryStats
extends 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

Method Summary

CountStatistic	getCommittedHeapSize() Returns the amount of memory in bytes that is committed for the JVM to use
CountStatistic	getCommittedNonHeapSize() Returns the amount of memory in bytes that is committed for the JVM to use
CountStatistic	getInitHeapSize() Returns the size of the heap initially requested by the JVM
CountStatistic	getInitNonHeapSize() Returns the size of the non=heap area initially requested by the JVM
CountStatistic	getMaxHeapSize() Returns the maximum amount of memory in bytes that can be used for memory management
CountStatistic	getMaxNonHeapSize() Returns the maximum amount of memory in bytes that can be used for memory management
CountStatistic	getObjectPendingFinalizationCount() Returns the approximate number of objects, that are pending finalization.
CountStatistic	getUsedHeapSize() Returns the size of the heap currently in use
CountStatistic	getUsedNonHeapSize() Returns the size of the non-heap area currently in use
