Splunk Add-on for Tomcat pattern not working

_joe — Mon, 09 Aug 2021 19:54:27 GMT

Hello all,

I was wondering if I could please get some suggestions on why Tomcat isn't honoring my pattern values. I am following the instructions here: https://docs.splunk.com/Documentation/AddOns/released/Tomcat/Recommendedfields

As recommended by Splunk documentation, we setup the following in className="org.apache.catalina.valves.AccessLogValve " in of server.xml

prefix="localhost_access_log_splunk" suffix=".txt"

pattern="%t, x_forwarded_for=?%{X-Forwarded-For}i?, remote_ip=?%a?,....

The filename and fields log as expected.

The only issue is instead of quotation (") marks, I am just seeing question marks (i.e. ...x_forwarded_for=?-?, remote_ip=?1.2.3.1?, remote_host=?1.2.3.2?,..)

Sorry, not really. It seems some Tomcat instances need to be escaped by something different, I'm no sure why.

How did you input those settings? Quotes are notorious for being "the wrong ones", especially when copy-pasted from an unknown source.
