Ah, that's for the tab delimited logs, not the json logs though.  I actually did it that way for years, I even have a python program that helps you generate the config:


But, I wouldn't use this method - the splunk TA app for bro is better.

As far as I know the transforms/props method only does the field lookups at search time, not at index time like the TA app configures.

Whenever the bro logs change and a column is added or removed, all those search time field lookups break.
