Exporting historical performance statistics
You can export historical performance statistics in CSV format to a file on the network. You can then import the data into a
spreadsheet or other third-party application.
The number of data samples downloaded is fixed at 100 to limit the size of the data file to be generated and transferred. The
default is to retrieve all the available data, up to six months, aggregated into 100 samples. You can specify a different time
range by specifying a start and end time. If the specified time range spans more than 100 15-minute samples, the data will be
aggregated into 100 samples.
The resulting file will contain a row of property names and a row for each data sample.
Export historical performance statistics
1. In the Performance topic, from the Show list, select Disks, Disk Groups, Virtual Pools, or Virtual Tiers.
2. Select at least one component.
NOTE: Statistics are exported for all disks, regardless of which components are selected.
3. Select Action > Export Historical Statistics.
The Export Historical Statistics panel opens.
4. To specify a time range, perform the following:
● Select the Time Range check box.
● Set date/time values for the starting and ending samples. The values must be between the current date/time and 6
months in the past. The ending values must be more recent than the starting values.
NOTE: If you specify a time range, it is recommended to specify a range of 24 hours or less.
5. Click OK.
NOTE:
In Microsoft Internet Explorer, if the download is blocked by a security bar, select its Download File option. If the
download does not succeed the first time, return to the Export Historical Statistics panel and retry the export operation.
6. When prompted to open or save the file, click Save.
● If you are using Firefox or Chrome and have a download directory set, the file Disk_Performance.csv is saved there.
● Otherwise, you are prompted to specify the file location and name. The default file name is Disk_Performance.csv.
Change the name to identify the system, controller, and date.
7. Click OK.
Resetting performance statistics
You can reset (clear) the current or historical performance statistics for all components. When you reset statistics, an event is
logged and new data samples will continue to be stored every five minutes.
Reset performance statistics
1. In the Performance topic, select Action > Reset All Statistics.
The Reset All Statistics panel opens.
2. Perform one of the following:
● To reset current statistics, select Current Data.
● To reset historical statistics, select Historical Data.
3. Click OK.
A confirmation panel appears.
4. Click Yes to continue. Otherwise, click No. If you clicked Yes, the statistics are cleared.
