ingest-time eval (creating new field dynamically on index time) not working

[agro1986001]

Hi. I tried the ingest-time eval documentation at (single enterprise instance):
https://docs.splunk.com/Documentation/Splunk/7.2.3/Data/IngestEval

However I could find the new field from the "| table eval_user" pipe. Does anyone have any experience in making it work? Thanks a lot

You can only do this if the city field exists as an indexed field, which almost certainly in your case, it does not. To test, try this search:

index=_* sourcetype=testlog city::*

If this returns no events the EITHER your sourcetype is not testlog (so your props.conf stanza header is wrong) OR city is not an indexed field. You can use something like this instead:

INGEST_EVAL = eval_city=lower(replace(replace(_raw, SuffixRegExHere), PrefixRegExHere, "")

What's your purpose of wanting to create an index time eval? There's more benefit of doing it at search time

Thanks for your reply

$ pwd
/Applications/Splunk/etc/system/local

$ cat transforms.conf
[myeval]
INGEST_EVAL = eval_city=lower(city)

$ cat props.conf
[testLog]
TRANSFORMS = myeval

$ cat fields.conf
[eval_city]
INDEXED = True

Here's my search

sourcetype=testLog
time=2019-01-27T15:23:02.664129+09:00 eventName=purchase userId=8304 city="London" item=food price=4200

And here's trying to get the ingest-time eval field

sourcetype=testLog | table userId, city, eval_city

but eval_city is blank

Any idea? Thanks a lot!

What version of Splunk are you using?

[richgalloway]

Have you also added to fields.conf?

[eval_city]
INDEXED = True

[richgalloway]

What are your props.conf and transforms.conf settings? What is the full query you're using to find the field?
