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 processors. In this case, the total processor time percentage is the average of the loads on each processor. • Busiest Processor Utilization %-The average utilization of the logical processor with the highest utilization. This value is equal to the Average Processor Utilization % if the server is using one processor core. • Processor Busy %-The percentage of time that the processor is executing a non-idle thread. • Context Switches/Sec-The number of thread context switches at which all processors on the server are switched from one thread to another each second. Context switches occur when a running thread voluntarily relinquishes the processor, is preempted by a higher-priority ready thread, or switches between user mode and privileged (kernel) mode to use a subsystem service. • Interrupts/Sec-The average number of hardware interrupts the processor is receiving and servicing each second.

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 processors. In this case,
the total processor time percentage is the average of the loads on each processor.
•
Busiest Processor Utilization %—The average utilization of the logical processor with the highest
utilization. This value is equal to the Average Processor Utilization % if the server is using one processor
core.
•
Processor Busy %—The percentage of time that the processor is executing a non-idle thread.
•
Context Switches/Sec—The number of thread context switches at which all processors on the server
are switched from one thread to another each second. Context switches occur when a running thread
voluntarily relinquishes the processor, is preempted by a higher-priority ready thread, or switches
between user mode and privileged (kernel) mode to use a subsystem service.
•
Interrupts/Sec—The average number of hardware interrupts the processor is receiving and servicing
each second.
Average Processor Utilization % and Highest Processor Utilization % are used to determine processor
performance.
Processors Inventory
•
Processor Support—Lists the number of processors supported by the server
•
Processors—Displays the number of processors installed on the server and a summary of the processors
(type, speed, and cache size)
SCSI adapter
The following information is provided for a SCSI adapter.
SCSI Adapter Status
•
Transfers/Sec—The number of requests between the server and this SCSI adapter each second
•
MBytes/Sec—The average number of megabytes transferred (read and written) between the server
and this SCSI adapter each second
•
Millisec/Transfer—The average time for each request to complete
•
Queue Length—The average number of concurrent requests between the server and this SCSI adapter,
including transfers currently being serviced and transfers waiting for service, regardless of where the
request is waiting (drive or adapter)
SCSI adapter performance is based on the performance of the SCSI disks attached to the adapter and the
SCSI buses used to attach the disks to the adapter.
SCSI Adapter InventoryController Configuration
•
Identifies the supported and negotiated PCI protocol (bus speed) used by the SCSI adapter
•
Provides the number of SCSI drives configured on the adapter
•
Provides the number of SCSI ports used
•
