Faults for Memory

Faults and related thresholds for Memory lists the faults detected for Memory.

Table 1. Faults and related thresholds for Memory

Memory Fault	Description	Threshold
ExcessiveFragmentation	Indicates that the system memory is highly fragmented and exceeds the Memory Fragmentation Threshold.	MemoryFragmentationThreshold
HighBufferMissRate	Indicates that the rate of buffer misses exceeds the Memory Buffer Miss Threshold. Drill down on this event notification in the Notification Log to view the percentage breakdown of buffer misses into the types of misses (such as small, medium, big, large, and huge buffer misses).	MemoryBufferMissThreshold
HighBufferUtilization	Indicates that the number of buffers used exceeds the Memory Buffer Utilization Threshold. Drill down on this event notification in the Notification Log to view the percentage of small, medium, big, large, and huge buffers used.	MemoryBufferUtilizationThreshold
InsufficientFreeMemory	Indicates that the system is running out of memory resources and that the percentage of free memory falls below the Free Memory Threshold. This fault is also reported if there has been a failure to allocate a buffer due to lack of memory.	FreeMemoryThreshold

When a memory-related fault occurs, IP Performance Manager generates a system ResourceException for the affected system. The thresholds for memory faults are listed in the Processor and Memory setting.
