A Measurement parameter matrix
This appendix details the measurement parameters evaluated by the performance management component
for the various components of a system configuration. A brief description of each parameter that appears,
in both the Status and Inventory view, is provided.
Server metrics
The following information is provided for server metrics.
Server status
• Average Processor Utilization %—The percentage of time that the processor is executing a non-idle
thread, averaged for the number of processors in the server
• Available MBytes—The amount of memory not currently allocated to any process (unused). A low
Available MBytes value might indicate memory allocation bottlenecks.
• Page Faults/Sec—The number of faulted pages handled by the processor each second
• Network MBytes/Sec—The sum of megabytes transferred (transmitted and received) over the subsystem
each second
• Storage MBytes/Sec—The sum of megabytes transferred (read and written) over the storage subsystem
each second
• Host Bus MBytes/Sec—The sum of megabytes transferred over the host buses each second

Processors
The following information is provided for processors.
Processors Status
▲ Average Processor Utilization %—The average percentage of time that all the processors on the system
are busy executing non-idle threads. On a multiprocessor system, if all processors are always busy, the
metric reads 100%; if all processors are 50% busy, the metric reads 50%; if one-fourth of the processors
