Measurement
Unit |
Interpretation |
| Avg_cpu_util |
This measurement indicates the percentage of utilization of the CPU time of the aggregate components. |
% |
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 see the exact cause of the problem.
|
| Avg_system_cpu_util |
Indicates the percentage of CPU time spent for system-level processing. |
% |
An unusually high value indicates a
problem and may be due to too many
system-level tasks executing
simultaneously
|
| Total_run_queue |
Indicates the instantaneous length of the queue in which threads are waiting for the processor cycle. This length does not include the threads that are currently being executed. |
Number |
A value consistently greater than 2
indicates that many processes could be
simultaneously contending for the
processor.
|
| Avg_swap_memory |
On Windows systems, this measurement denotes the committed amount of virtual memory. This corresponds to the space reserved for virtual memory on disk paging file(s). On Solaris systems, this metric corresponds to the swap space currently available. On HPUX and AIX systems, this metric corresponds to the amount of active virtual memory (it is assumed that one virtual page corresponds to 4 KB of memory in this computation). |
MB |
An unusually high value for the swap
usage can indicate a memory
bottleneck. Check the memory
utilization of individual processes to
figure out the process(es) that has
(have) maximum memory consumption
and look to tune their memory usages
and allocations accordingly.
|
| Avg_free_memory |
Indicates the free memory available. |
MB |
A very low value of free memory is also
an indication of high memory utilization
on a host. The detailed diagnosis of this
measure lists the top 10 processes
responsible for maximum memory
consumption on the host.
