VM Status (PI_VI)
- Organization of this page
Function
This record stores performance data on a virtual machine over a unit of time. This record is a multi-instance record.
In this record, you can collect performance data such as CPU usage by the virtual machine, CPU insufficiency, and CPU allocation. The figure below shows an example of data that can be collected in this record.
