Is there more detailed information about how the CEF field mapping works?
I've tried the cef_field_map statement in the realtimeoutput.conf, but that doesn't work and the dragndrop in the gui also does not map any fields.

The only thing that seems to work is to use the eval statement in the search to create fields that match the original cef field names. Then the Real-Time Output app will output them.

Is there anyone who has some experience or who has a manual?

Cheers,
Ger

I managed to get it working by looking at the python scripts. You need to use cef_field_map rather than cef_override_map. I did a test using splunk's web_access.log see below

index=_internal source="*web_access.log" | eval cef_field_map="host:dvchost,source:fname,spent:cn1,useragent:cs1,user:duser,status:cn2,clientip:dvc,method:cs2,bytes:cn3"

I would upload screen shots, but the web site is not allowing me to as apparently I don't have sufficient karma 🙂

Ger,
Here is where you can find the (lastest) revision 20 of the "Implementing ArcSight CEF" document. Implementing ArcSight CEF.pdf
You may need to register with ArcSight to view.
