First I would check the version of AutoPass License Server (APLS) you have. If it is not 9.2.1 or higher I would recommend upgrading now.
Getting license history can be done by going to the APLS web portal and clicking on the ''License Usage'' tab. Then clicking on the ''Feature ID:Version'' that is desired for reports. The page will change and then click on the ''History'' tab. The history is shown for last 30 days (default) but, it can be changed by going to the ''Date Range '' area and changing the date that the report covers. Also you can filter by user pool. Once the data is displayed at the bottom the page the data can be ''exported to Excel'' by using the link in the top right corner of the frame.
