Deleted Item Tracking in ArcGIS Online

[GJY]

I manage an AGOL organization with almost 500 users spread out among many departments in my organization.  Each department is allotted a certain number of service credits based on the size of its user base.  I am trying to track credit usage by department.  I can get most of the detail I need through the Python API and the AGOL status interface.  What I cannot track (at least to my knowledge) is credit usage by items that have been deleted.  

I would like to have the ability to report on deleted items that consumed service credits, including how many credits they consumed and who created them (through the Python API and AGOL interface).
