On the Desktop Capacity and Model Definition Page, you can download the Customer Usage Report and the User Activity License Report.
Customer Usage Report
To download the Customer Usage Report, click the Download Usage Report link under the Standard Capacities list on the left of the page.
The report downloads in .csv format.
The Usage Report shows data for overall capacity quantity and quantities for sub-types, such as Appstacks.
User Activity License Report
To download the User Activity License Report, select the date range, VM type (or 'all' for all VMs), and Organization ID (or 'all' for all orgs), and then click the Download button.
A zip file downloads containing multiple .csv files: a General Report and a report for each VM type you selected.
The General Report shows peak concurrent users and number of unique users, along with any errors, for selected orgs. The vGPU and/or winServer reports show date, user ID, and VM accessed for selected orgs.
