For analyzing statistic information, specify settings to accumulate statistic information history files on the iSM
Management server first. By summarizing, extracting, and editing the accumulated statistic information history files
on the iSM Management server, the statistic information history is managed. Otherwise, by downloading the
accumulated statistic information files and summarizing, extracting, and editing the data on the hard disk of an iSM
client, the statistic information history is managed.

To accumulate statistic information in a file by using this function, the following requirements for the accumulation of
statistic information must be met.
It is a disk array which is registered as a target of control by the iSM server.
It is a disk array which is a target of monitoring by the iSM server.
The following methods are available for controlling the operation of accumulating statistic information of the disk
arrays which satisfy the above requirements.
Method for using the iSMprflog command
Method for controlling from the real-time display screen
Method for performing settings in the environment definition file
Each method will be described below.
(1) Operations by using the iSMprflog command
(i)
Storing of statistic information
Two methods are available to start the accumulation of statistic information: a method for specifying a specific
disk array and a method for specifying all the disk arrays monitored by the iSM server simultaneously.
To start the accumulation of statistic information of a specific disk array, assign a disk array name to the end of -d
option and then execute the iSMprflog start command. For example, when you start the accumulation of
statistic information of a disk array (NECStorage4100), perform the operation below.
iSMprflog start -d NECStorage4100
If the specified disk array does not satisfy the requirements for accumulating statistic information or if statistic
information is being accumulated, activating this command results in fault.
On the other hand, when you start the accumulation of statistic information of all the disk arrays which satisfy the
above requirements and for which statistic information has not been accumulated, perform the operation below.
iSMprflog start -a
