Host Physical Disk Status (PI_HPDI)

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.

Note:
Information cannot be collected if an attempt to connect to the monitored physical server fails.

#
The value used in [[Figure]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.
