VM Memory Status (PI_VMI)
- Organization of this page
Function
This record stores performance data on virtual memory being used by 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 details about the memory being used by the virtual machine and memory allocation. You can also collect performance data on the swap that the virtual machine is using. The figure below shows an example of data that can be collected in this record.

The value used in [±hh:mm] varies depending on the time zone of the monitored host. For example, if the monitored virtual environment is operating according to JST, +09:00 is displayed. If the monitored virtual environment is operating according to UTC, Z is displayed.
