Overview of Export Tool
The Export Tool enables you to export monitoring data (that is, statistics) that can display in the Auto
LUN window to text files. The Export Tool also enables you to export monitoring data on remote copy
operations performed by Continuous Access, TrueCopy for Mainframe, Continuous Access Journal,
and Universal Replicator for Mainframe. If you export monitoring data to text files, you can import
the monitoring data into word processor documents. You can also import the monitoring data into
spreadsheet or database software to analyze the monitoring data.
Figure 3 on page 22 is an example of a text file imported into spreadsheet software:
Transfer rates for LUs (Filename: LU_IOPS.csv)
Indicates that the subsystem serial number is 60001.
The word in parentheses is a code that indicates the subsystem type.
Indicates that the data was obtained from 18:57 to 19:01 on March 28,
2007. Sampling rate: 1 indicates that monitoring was performed
every minute (at a one-minute interval).
Indicates monitoring data. If a value is -1, the value indicates
that Performance Monitor failed to obtain the data for some
reason. For detailed information, refer to the troubleshooting
information later in this appendix.
Notes:
• In this LU_IOPS.csv file, the last four digits of a table column heading (such as 0001 and 0002) indicate an
LUN. For example, the heading CL1-A.00(1A-G00).0001 indicates the port CL1-A , the host group ID 00, the
host group name 1A-G00, and the LUN 0001.
•
If you export monitoring data about concatenated parity groups, the resulting CSV file do not contain column
headings for the concatenated parity groups. For example, if you export monitoring data about a
concatenated parity group named 1-3[1-4], you will be unable to find 1-3[1-4] in column headings. To locate
monitoring data about 1-3[1-4]
,
find the 1-3 column or the 1-4 column. Either of these columns contains
monitoring data about 1-3[1-4].
Figure 3 An Example of a Text File
Notes:
• When you run the Export Tool, text files are usually compressed in a ZIP-format archive file. To
open a text file, you must use decompress the ZIP file to extract the text files.
• Text files are in CSV (comma-separated value) format, in which values are delimited by commas.
Many spreadsheet applications can be used to open CSV files.
• Do not run multiple instances of the Export Tool simultaneously. If you run multiple instances, the
SVP may be overloaded and a timeout error may occur.
