Host Physical Disk Status (PI_HPDI)
- Organization of this page
Function
This record stores performance data on a physical disk of a physical server over a unit of time. This record is a multi-instance record.
In this record, you can collect performance data such as data read/write speed on a physical disk of a physical server. For the data read/write speed, you can collect further details, that is, data read speed and data write speed. The figure below shows an example of data that can be collected into this record.
