(2) Statistic information record
This record contains statistic information for each component of the disk array. There are the
following types of statistic information records.
Statistic information record of a host port (a port of the host director)
Statistic information record of a disk port (a port of the disk director)
Statistic information record of a physical disk
Statistic information record of a logical disk
Statistic information record of a RANK
The record formats of the statistic information records are described below. "Save location" in
the table indicates the order of the data separated by commas in the record. The save location of
the leftmost data is 1. If the type of statistic information is specified as an extraction condition
and the data is excluded from the targets of extraction, or if data does not exist, the save location
of the data does not change. In this case, only a comma is written to the location.
"Period of Accumulation" and "Period of Summarizing" in the table have the following meaning
respectively.
Accumulation Period
The period in which statistic information of the statistic information history file is
accumulated. It corresponds to logging interval time.
Summarizing Period
The period in which statistic information of the statistic information history file is
summarized. It is either 1 hour or 1 day.
The shaded parts in the table are provided only when statistic information of the statistic
information summarized file is extracted.
