![]() In Splunk 6, we’ve replaced this with the stanza INDEXED_EXTRACTIONS = w3c. In previous versions of Splunk, this is where you would see the (not working so well) CHECK_FOR_HEADER = True. Now IIS is what we call a pre-trained sourcetype so if you go look in $SPLUNK_HOME/etc/system/default/nf you will see something that looks like this So for our IIS example, I would put the following in nf out on my Universal Forwarder: Good news! In Splunk 6 we’ve added several nf stanzas to better handle the diversity of header formats out there and make this mapping of field values found in headers easier. Moreover, if you were monitoring a file with a header using a Universal Forwarder, the props/transforms/learned magic happened locally on the Forwarder and did not get transmitted to your indexing or search tier making this quite a manual process. #Fields: date time s-ip cs-method cs-uri-stem cs-uri-query s-port cs-username c-ip cs-version cs(User-Agent) cs(Cookie) cs-host sc-status sc-substatus sc-win32-status sc-bytes cs-bytes time-taken #Software: Microsoft Internet Information Services 7.5 ![]() While this worked ok for local file ingestion on a Splunk server for CSV, CHECK_FOR_HEADER would get confused with multi-line headers like those found in IIS. Historically, if you were going to Splunk anything with a file header, like a CSV or IIS log, we attempted to take the file header, read in the field names, and create a props and transforms for you in the learned app using DELIMS. With all the buzz around Data Model and Pivot, you might have missed a few of the other cool things we’ve been working on back in the bit factory. Needless to say, we delivered a feature packed release in Splunk 6 a few weeks ago.
