Citrix XenServer 6 Operating System Total Percent Processor Time Monitor
This monitor checks the CPU utilization. If you receive an alert from this monitor, action can be required in order to bring the System back to an operational state.
An unhealthy state indicates that the CPU utilization is currently high. This may be caused by an application using excessive CPU resources.
To address high percent processor times choose one or more of the following options:
Identify processes that are running when the Percent Processor Time is at the highest. Execute the "top" command or execute "Top 10 CPU Processes" Task from the State View. It will provide a listing of processes ordered by CPU usage, the listing by default will display only the top CPU consuming processes and their corresponding PID (Process ID).
Stop or kill any unnecessary identified processes. Utilizing the output from the "top" command identify any offending or unnecessary processes along with its PID number. Issue a "kill" command utilizing the PID for the process. For example, if the PID number for the process is 4510, then issue the command 'kill 4510'.
Add additional CPUs or Physical Memory to the computer.
Move applications to one or more additional servers.
You may view the Top CPU Consumers by executing the "Top 10 CPU Processes" Task from the State View.
