End gathering port data
By default, the system compresses monitoring data files into a ZIP-format archive file. When you
want to view the monitoring data, you can decompress and extract the CSV files from the ZIP
archive. If the operating system on your computer does not include a way to extract files from a
ZIP archive, you need to obtain software to view the data.
NOTE: You can change the default method of exporting files to an uncompressed format. However,
the resulting files could be significantly larger and take longer to compile. For more information,
see option Subcommand
“option” (page 118) .
For a complete list of files to be saved by the Export Tool, see “Using the Export Tool” (page 92) .
File formats
If you specify the nocompress operand for the option subcommand, the Export Tool saves files
in CSV format instead of ZIP format (For detailed information, see option Subcommand
“option”
(page 118) ). When files are saved in CSV format instead of ZIP format, the file saving process could
take longer and the resulting files could be larger.
Processing time
Files saved by the Export Tool are often very large. The total file size for all files can be as large
as approximately 2 GB. For this reason, the exporting process might take a lot of time. If you want
to export statistics spanning a long period of time, it is recommended that you run the Export Tool
multiple times for different periods, rather than run it one time to export the entire time span as a
single large file. For example, if you want to export statistics spanning 24 hours, run the tool eight
times to export statistics in three 3- hour increments.
The next table provides lists time estimates for exporting monitoring data files using different
operands in the group subcommand:

• The Export Tool should save statistics about 8,192 volumes within a
24-hour period.*
•
The Export Tool is used eight times. Each time the Export Tool is used,
the tool obtains statistics within a 3-hour period.

•
The Export Tool should save statistics about 12,288 LUs within a
24-hour period.*
• The Export Tool is used eight times. Each time the Export Tool is used,
the tool obtains statistics within a 3-hour period.
*For a 1-minute interval, the number of hours for the data that is stored is proportional to the interval. For example,
for a 2-minute interval, data for 48 hours can be stored.
