Hi

I'm filtering windows events from the Heavy Forwarder, everything works fine, all events are filtered except for EventCode = 0 any idea why?

EventCode 0 was not being filtered because it is an Application event and not a security event.

In this way I solved it

 

props.conf

[source::WinEventLog:Application]
TRANSFORMS-wmi = setnull2

 


transforms.conf

[setnull2]
REGEX= (?msi) ^EventCode=(0)
DEST_KEY=queue
FORMAT=nullQueue

We were able to filter it out from the UF using the following in our inputs.conf:

[WinEventLog://Application]
disabled = 0
index = windows_index
blacklist1 = EventCode="0"
