D.3 storageadm perfdata (Command for managing performance information)

This section explains the command for managing the operating environment.

NAME

storageadm perfdata - Management of performance information.

SYNOPSIS

$INS_DIR\Express\Manager\bin\storageadm perfdata export outdirname -ipaddr ipaddr [-recent 24]

($INS_DIR means "Program Directory" specified at the Express Manager installation.)

DESCRIPTION

This command outputs one-hour or 24-hour performance information for disk storage system before the command is executed.

By specifying the IP address of a disk storage system whose performance information is output and the time in the command operand, the disk storage system performance information is output in CSV format.

A target disk storage system must be managed by Express and performance monitoring is either still running or already completed.

The details of CSV files are as follows.

OPERANDS

export: Outputs performance information for the specified time in CSV format.

outdirname

Specify the directory that outputs performance information.
Performance information is output to the outdirname directory based on the following configuration.

The following free space is required for this directory.

(((0.1 + 0.4 * installed DEs + 0.1 * installed CM ports + 0.2 * (LUs + RAID grous)) * (86400 / 60)) + (0.2 + 0.6 * installed DEs + 0.2 *installed CM ports + 0.4 * (LUs + RAID groups))) / 1024

OPTIONS

-ipaddr ipaddr

This option specifies the IP address of the device that outputs performance information.

The output target device must satisfy the following conditions:

Storage devices output performance information must be registered in this software.

For the settings of performance monitoring, refer to "Performance management".

-recent 24

This option collects the latest 24-hour performance data.

If this option is skipped, the latest 1-hour performance data is collected.

EXAMPLES

Output of performance information for a device with IP address 10.12.13.14 to the c:\work directory:

> storageadm perfdata export "C:\work" -ipaddr 10.12.13.14

NOTES

The full path of an existing directory must be specified in outdirname.
