Open Worksheets may be saved for at least these reasons:
To create custom performance views which display statistics of interest.
To investigate performance events for later analysis. A worksheet may be paused on a particular event and then saved, so that others can open the worksheet later and study the event.
The following properties are stored for saved worksheets:
|
Mouse over saved worksheet entries to expose the following controls:
|
Single click an entry to open that worksheet. This may take several seconds if the worksheet was paused on a time in the distant past, or if it spanned many days, as the appliance must read the statistic data from disk back into memory.
Worksheet maintenance actions are available under the analytics worksheets context. Use the show to view the current saved worksheets:

Worksheets may be selected so that more details may be viewed. Here one of the statistics is dumped and retrieved in CSV format from the saved worksheet:

If there was a need to gather Analytics statistics using an automated CLI script over SSH, it would be possible to create a saved worksheet containing the desired statistics which could then be read in this fashion. This is one way to view analytics from the CLI; also see Reading datasets.
