File formats

If you specify the nocompress operand for the option subcommand, Export Tool saves files
in CSV format instead of ZIP format (For detailed information, see
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 Export Tool are often very large. The total file size can be as large as 2 GB.
Therefore, you might need a lot of time to complete the exporting process. If you want to export
statistics spanning a long period of time, you should run Export Tool multiple times for shorter
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-hour increments.
The following table provides lists time estimates for exporting monitoring data files using different
operands in the group subcommand.

* 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.
Note:
The estimated time that includes the transfer time of the network might take a lot of time, depending on the
transmission speed of the network.
To shorten the acquisition time, specify the option of the group command to narrow acquisition objects. For
details about the group command, see

Termination code

If you want to use a reference to a termination code in your batch file, perform the following
actions:
To use such a reference in a Windows batch file, write %errorlevel% in the batch file.
To use such a reference in a UNIX Bourne shell script, write $? in the shell script.
To use such a reference in a UNIX C shell script, write $status in the shell script.
A reference to a termination code is used in the following example of a Windows batch file. If this
batch file runs and Export Tool returns the termination code 1 or 3, the command prompt displays
a message that indicates the set subcommand fails.
