% CPU Utilization In System Mode (CPUSysTime )
Description
This parameter displays the percentage of CPU time spent in system mode doing system tasks, including the CPU resources consumed by calls to kernel routines.
By itself, the CPUSysTime parameter does not give you much information. However, when combined with information from the MEMPageOut, MEMPFault, CPUUserTime, and CPUWio parameters, you can get a better understanding of possible problems in your system.
If CPUSysTime is high relative to CPUUserTime, then the CPU is either executing a large number of kernel routines or your system is running out of memory.
Default Action Taken by PATROL
None.
Recommendations
If CPUSysTime and MEMPageOut (and/or MEMPFault) are all high, then you should try to identify which processes are causing this condition. If the offending processes are common processes that are run often, then your system's performance could be improved by adding more memory.
The defaults (Warning in the 90% to 95% range and Alarm in the 95% to 100% range) are reasonable for a typical system. However, knowing the characteristics of your system and its work load will help you determine whether or not to change the defaults.
