Hi Health,
Apologies for the late follow up. It took some time to track down an answer on your question.
> Is there a way to export usage as a pdf from portal 10.6.1...
From the Dev team, "We do not expose the usage statistics used on the 'status' page. You can gather general statistics using the User object, Item object, Item.usage() and gis.admin.history() via custom scripts with the Python API. Some users will store these daily statistics in a hosted table and aggregate the data to fit their needs."
Hope this helps and thanks for your patience,
