I am using the SharePoint Audit Query to build a custom audit log system.
For each hit, I need also the machine name or machine IP.
On the object SPAuditEntry there are two MachineName and MachineIP but are always empty.
From MSDN documentation (https://msdn.microsoft.com/en-us/library/microsoft.sharepoint.spauditentry.machineip.aspx) :
In SharePoint Foundation, this property is always a null reference
I am using SP2013 Enterprise on prem.
How can I get these information?
