KPIs
The following table describes the ISSystemComponent.java.lang.type.MemoryPool KPIs.
Name
Description
boolean ObjectStatus
Online if the MemoryPool MBean type exists.
boolean CollectionUsageThresholdSupported
Tests if the memory pool supports a garbage collection usage threshold.
long PeakUsage.committed
Returns the size of memory that is committed for peak usage (in bytes).
long PeakUsage.init
Returns the size of memory that the Java virtual machine initially requests from the operating system for peak usage (in bytes).
long PeakUsage.max
Returns the maximum size of memory that can be used for peak usage (in bytes).
long PeakUsage.used
Returns the size of the memory that is used for peak usage (in bytes).
long Usage.committed
Returns the size of memory that is committed for the memory pool (in bytes).
long Usage.init
Returns the size of memory that the Java virtual machine initially requests from the operating system for the memory pool (in bytes).
long Usage.max
Returns the maximum size of memory to be used for the memory pool (in bytes).
long Usage.used
Returns the size of memory used for the memory pool (in bytes).
long UsageThreshold
Returns the value of the usage threshold for the memory pool (in bytes).
long UsageThresholdCount
Returns the number of times that the memory usage was higher than the usage threshold.
boolean UsageThresholdExceeded
Tests if the memory usage of the memory pool reaches or exceeds the usage threshold of the memory pool.
boolean UsageThresholdSupported
Tests if the memory pool supports usage threshold.
boolean Valid
Tests if the memory pool is valid on the Java virtual machine.
