Requestor upn is missing in azure file share event data

Naija R C 0 Reputation points


I am looking for retrieving user information from the REST API azure file share event's JSON object.

The required user details can be found using the Requestor/UPN value.

Reference link: documentation for Azure Files monitoring data reference

But while getting the REST API azure file share event's JSON object , I am not getting the Requestor/UPN value. So, What is the way to get Requestor/UPN parameter value in my event details? How to do that?

I have given the sample event details which I got for create file share event:

    @Naija R C we will only gather the UPN in certain criteria. In general, you should use callerip to track back down to a specific workstation. "

      "callerIpAddress": "XXXXX",

    If the user used SAS, they'll see an IP address. You'd get a UPN if using a supported Authentication type that pulls UPN like ADDS or AADDS, etc. If you connect via storageaccount/key or SAS then you'll get the Caller IP address.

    Hope this helps. Please let us know if you have any more questions and we will be glad to assist you further. Thank you!
