VM Virtual Disk Status (PI_VVDI)
- Organization of this page
Function
This record stores performance data on a virtual disk 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 the data read/write speed of the virtual disk being used by the virtual machine. For the data read/write speed, you can collect further details, that is, data write speed and data read speed. The figure below shows an example of data that can be collected in this record.
- Note:
-
Information cannot be collected if an attempt to connect to the monitored physical server fails.
