ZVM_Total_to_Virtual_High

Raises an alert when the ratio of total CPU time used to virtual CPU time used is greater than or equal to 2. This ratio is the mean total to virtual ratio of all virtual machines on the system and indicates how much processor overhead is incurred for virtual machine processing. A lower total to virtual ratio means less processor time has been used by the Control Program and more time has been used by virtual machine processing. This situation must be started manually.

Review the Total to Virtual Ratio linear gauge chart in the System workspace. See also the USER screen of the Performance Toolkit. This screen displays the mean T/V Ratio.

Consider changing the thresholds used in this situation as they may not be appropriate for your installation.

The following shows the formula for the ZVM_Total_to_Virtual_High situation:
