Processor and Memory threshold setting

The Processor and Memory threshold setting configures the performance monitoring of a system’s processor and its associated memory objects. Parameters in this setting control the notification of these faults:

• High Utilization

• High Backplane Utilization (Chassis)

• High Buffer Miss Rate

• High Buffer Utilization

• Fragmentation

• Insufficient Free Memory

  Default values for the Processor and Memory threshold setting lists the Processor and Memory threshold setting parameters.

Table 1. Default values for the Processor and Memory threshold setting

Parameter	Default value	Description
BackplaneUtilizationThreshold	0 to 100% Default: 80%	Upper threshold for a switch’s backplane utilization expressed as a percentage of the total backplane bandwidth.
FreeMemoryThreshold	0 to 100% Default: 15%	Lower threshold for the acceptable amount of free memory as measured by the ratio of free memory to the total memory.
MemoryBufferMissThreshold	0 to 100% Default: 10%	Upper threshold for the number of buffer misses, expressed as a percentage of the total number of buffer requests.
MemoryBufferUtilization-Threshold	0 to 100% Default: 90%	Upper threshold for the number of buffers that are used, expressed as a percentage of the total number of buffers.
MemoryFragmentation-Threshold	0 to 100% Default: 5%	Lower threshold for memory fragmentation. The fragmentation value is the ratio of the largest number of contiguous unallocated bytes to the total amount of free memory. For example, a value of 5 indicates that the largest free buffer must be at least 5% of the free memory.
ProcessorUtilizationThreshold	0 to 100% Default: 90%	Upper threshold for processor utilization, expressed as a percentage of the total capacity of the processor.
