Monitors the average CPU utilization on a virtual machine and alerts if the utilization is over the threshold for a specific number of samples.
The average CPU utilization on a virtual machine is high.
The following configuration parameters are customizable:
IntervalSeconds - The recurring interval of time in seconds in which to run the script (the default value is set to 300 seconds).
NumberOfSamples - The number of event occurrences before monitor state changes will be triggered (the default value is set to 3).
Threshold - The value that defines the warning threshold to be used in the comparison (the default value is set to 85 percentage).
The virtual machine may be highly utilized.
Consider the following solutions to reduce the average CPU utilization:
Check whether the average CPU utilization on the virtual machine is high for longer periods of time. If yes, consider adding more CPUs to it or migrate it to a more powerful server.
Check whether an application running on a virtual machine is unnecessarily consuming resources.
Occasional average CPU utilization peaks are okay as long as the long term average CPU utilization on a virtual machine is not more than 80%. The long term CPU utilization of more than 80% typically indicates an overloaded virtual machine.
For more information on how to add more CPUs to the virtual machine or how to migrate virtual machines to other servers, see the “Citrix XenServer Administrator’s Guide”.
