(2) CSV Conversion Tool
The CSV Conversion Tool extracts statistic information from the statistic information history/summarized files of
iSM and turns it into character string data for output in the CSV format. Spreadsheet software, etc. is used to
display the contents of a CSV-format output file in a graph or to make various types of analysis later.
(3) Performance Report Editor
The Performance Report Editor edits and modifies the statistic information stored in statistic information
history/summarized files of iSM into a format that allows the user to readily make performance analysis, and
outputs the resulting information as a file. Editing the statistic information by using the Performance Report
Editor assures easy and proper performance analysis.
For how to use performance analysis support tools, refer to the following sections of the “PerformanceMonitor
User’s Manual”.
Archiver - 3.3.3 “Summarizing Statistic Information”
CSV Conversion Tool - 3.3.4 “Extracting Statistic Information”
Performance report Editor - 3.3.5 “Editing Statistic Information”
To perform efficient operation of the disk array, it is advantageous to grasp long-term load and analyze long-term
performance. The iSM cyclically reads the statistic information collected by the disk array and stores the
information obtained into a statistic information history file.
Performance analysis supporting tools support analysis of such statistic information via the following functions.
y Summarizing the statistic information history file into statistic information in a section that is longer than a
logging interval to create statistic information summarized file with compressed file capacity (Archiver).
y Outputting necessary statistic information from a statistic information history file or statistic information
summarized file in the CSV format to make available the resulting information to spreadsheet software, etc.

For details of how to use Performance analysis support tools, refer to 3.3.3 “Summarizing Statistic Information”
and 3.3.4 “Extracting Statistic Information” in the “PerformanceMonitor User’s Manual”.

If a possible cause of a fault is not known after the iSM server has abnormally terminated, it is necessary to analyze log
and trace information.
The function of information collection in the event of an iSM fault, collects log and trace information under the
iSMgather directory of the directory where the iSM server is installed (typically c:\Program
Files\NEC\iSMsvr\iSMgather).
For measures against a fault, refer to 6.1 “Measures for Server Fault”.
