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
Server inventory
•
Server model
Processor quantity and description ◦
◦ Amount of memory
◦ Network adapters and ports
◦ Storage controllers/SCSI adapters
◦ Host buses
•
Operating system
Server operating system and version information ◦
◦ Summary of the file systems defined on the operating system
◦ Number of processors in use
◦ Windows and Linux physical disks
◦ Displays server specific memory recommendations (for G7 servers and above), if any
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 are busy, the metric reads 25%. Average Processor Busy
% can be viewed as the fraction of the time spent doing useful work.
Each processor is assigned an idle thread in the idle process consuming unproductive processor
cycles not used by another thread. Some processors might be more heavily loaded than other
