I came across http://answers.splunk.com/answers/174939/why-are-my-json-fields-extracted-twice.html which seemed to describe perfectly the issue, but I've been unable to resolve - as far as I can see, KV_MODE is already set to none.
On our collectors, we have an app with props.conf as follows:
[fundapps_logs]
SHOULD_LINEMERGE = false
TIMESTAMP_FIELDS = datetime
TIME_FORMAT = %m-%d-%Y %H:%M:%S.%l
INDEXED_EXTRACTIONS = json
TRUNCATE = 20000
KV_MODE = none
however, we see two sets of fields in results when we search (but not for the built in splunk fields). If I then do
sourcetype=fundapps_logs | extract
I then see three sets of fields in results. I'm guessing I've got a config issue somewhere.
I've tried adding the same app and props.config to the splunk search/web head (everything runs on a single machine), and restarting but it doesn't appear to have any impact.
Any suggestion?
Did you deploy this to your Indexers and after that did you restart all Splunk instances on the Indexers?
Not sure if you still have this problem, but the answer to this problem is here
