Splunk Add-on for Microsoft IIS - ms:iis:auto - No Fields Extracted

[iamperson347]

Hi All,

I've followed the instructions here (https://docs.splunk.com/Documentation/AddOns/latest/MSIIS/About) to ingest MS IIS logs into splunk. I have installed the universal forwarder on our test windows server, as well as the IIS Splunkbase app on the windows server and our heavy forwarder. (Our heavy forwarder is configured to forward upstream.)

For inputs on the test windows server, we have this configured:

C:\Program Files\SplunkUniversalForwarder\etc\apps\Splunk_TA_microsoft-iis\local\inputs.conf

[monitor://C:\inetpub\logs\LogFiles]
disabled = 0
index = test_index
sourcetype = ms:iis:auto

Example of the IIS log:

#Software: Microsoft Internet Information Services 8.5
#Version: 1.0
#Date: 2020-09-18 13:15:43
#Fields: date time s-ip cs-method cs-uri-stem cs-uri-query s-port cs-username c-ip cs(User-Agent) cs(Referer) sc-status sc-substatus sc-win32-status time-taken

Data from Splunk Search:

Any idea on why fields aren't being extracted? Not even host is being extracted. Other logs from our windows servers work fine, this is the only app/log type we are currently having trouble with.

Issue was with the search itself - not the fields from the app.

Try installing the IIS add-on on your search head(s).

Hi @richgalloway 

It looks like it is already installed on the search heads.
