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:

*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:
