Hi @SplunkDash,

the problem is surely that you have a duplicated group name (Type), but there's also another problem that you haven't using somethng like this:

^(?P<UserID>\w*)\|(?P<UserType>\w*)\|(?P<System>\w*)\|(?P<EventType>\w*)\|(?P<EventId>[^\|]*)\|(?P<Subject>[^\|]*)\|(?P<SID>[^\|]*)\|(?P<IPAddr>[^\|]*)\|(?P<EventStatus>[^\|]*)\|(?P<Msg>[^\|]*)\|(?P<TimeStamp>[^\|]*)\|(?P<DATA>[^\|]*)\|(?P<Period>[^\|]*)\|(?P<MCode>[^\|]*)\|(?P<Type>[^\|]*)\|(?P<Type2>[^\|]*)\|(?P<DeviceId>[^\|]*)\|(?P<DesIP>[^\|]*)\|(?P<Code>[^\|]*)\|(?P<Headers>.*)

Hello @gcusello ,

I implemented your updated REGEX/REX through SPLUNK web interface, it's extracted as expected and showing no errors in preview. But no/any extracted fields are not showing up from search head.  Any thoughts? Thank you so much again and any recommendation would be helpful.
