Description |
Measurement
Unit |
Interpretation |
| Processor_usage |
Processing
load on this processor for the last second, expressed as a percentage |
Percent |
A
high value could signify a CPU bottleneck. The CPU utilization may be
high because a few processes are consuming a lot of CPU, or because
there are too many processes contending for a limited resource. Check
the currently running processes to figure out the exact cause of the
problem.
|
| Processor_interrupt_rate |
The
average rate per second at which the processor handles interrupts from
applications or hardware devices |
Interrupts/Sec |
High
interrupt rates can indicate hardware problems. Compare this value
with CPU usage. If this value increases dramatically without a
corresponding increase in system activity, it can indicate a hardware
problem.
|
| Processor_interrupt_time |
Amount
of time that the processor spent receiving and servicing hardware
interrupts during the measure interval |
Secs |
This
value is an indirect indicator of the activity of devices that
generate interrupts, such as the system clock, the mouse, disk
drivers, data communication lines, network interface cards and other
peripheral devices. These devices normally interrupt the processor
when they have completed a task or require attention. A high value
indicates a hardware problem.
|
| Processor_threads |
The
total number of threads in the processor |
