Answer

MemoryBufferMissThreshold is a configurable value in polling and threshold tab of system group in the processor and memory tab. The default value is 10 and it can be configured till 100.

All the configured values are directly taken as the upper threshold for the number of buffer misses and expressed as a percentage of the total number of buffer requests.

While calculating the event HighBufferMissRate, the value set in MemoryBufferMissThreshold will be used when:

The number of buffer misses that exceeded its threshold and if BufferMissThreshold is less than 100

Also, check if BufferMissPct is greater than BufferMissThreshold.

The event HighBufferMissRate indicates the rate of buffer misses that exceeds BufferMissThreshold.
