@Michael_Soprano you want to chek if a file copied to the DLZ correctly?
You should be able to list the files with azcopy, something like:
azcopy list "<containerURL>"
If on the other hand, you want to monitor if AEP actually ingested the data from the DLZ, the AEP UI monitoring is probably the best option here to be able to narrow down on the actual source and its dataflow runs.
Let me know if that helps
