Forwarded Events / Subscriptions missing information in EventData section

    Question

  • Hi

    Am trying Event Subscriptions to send security logs from several servers to one central server

    The events get forwarded okay, but for some reason some of the information in EventData is missing when I view the log in ForwardedEvents, but if I look back on source server it definitely exists

    Below image shows example, as you can see several fields missing information and things like IP Address showing in Process Name field rather than where it should be

    Second image shows XML of the same event where information is correct

    Any ideas?


    EDIT - meant to say using Server 2008 R2

  • Have now repeated same test on Server 2016 and exactly the same problem - forwarded event is missing half the information compared to original event, message just shows %11, %12, %13 etc

    Tried changing locale from en-GB to en-US and doesn't work

    Tried changing ContentFormat from RenderedText to Events and still same problem

    Please any ideas? as this seems a deal breaker with event forwarding and from testing looks like affects multiple version of Windows

  • Below shows the original event in security log:-

    This event is generated when a logon session is created. It is generated on the computer that was accessed.
    
    The subject fields indicate the account on the local system which requested the logon. This is most commonly a service such as the Server service, or a local process such as Winlogon.exe or Services.exe.
    
    The logon type field indicates the kind of logon that occurred. The most common types are 2 (interactive) and 3 (network).
    
    The New Logon fields indicate the account for whom the new logon was created, i.e. the account that was logged on.
    
    The network fields indicate where a remote logon request originated. Workstation name is not always available and may be left blank in some cases.
    
    The impersonation level field indicates the extent to which a process in the logon session can impersonate.
    
    The authentication information fields provide detailed information about this specific logon request.
    	- Logon GUID is a unique identifier that can be used to correlate this event with a KDC event.
    	- Transited services indicate which intermediate services have participated in this logon request.
    	- Package name indicates which sub-protocol was used among the NTLM protocols.
    	- Key length indicates the length of the generated session key. This will be 0 if no session key was requested."
    

    And this shows the same event in forwarded events logs:-
