Dear Tomcat support, I am a developer working on Java applications and have been using different containers and deployment platforms. I would like to have a question on the access logs.
The access logs of Tomcat is configured in $TOMCAT_HOME/conf/server.xml, the "Valve" attribute with className="org.apache.catalina.valves.AccessLogValve". The format of log is governed by the pattern expression, referenced in the documentation of Tomcat (TOMCAT_URI/config/valve.html). Is it possible to format the log with customized field name and string contents? I've been looking for answer in the web but no clear answer is found. I read through the usage / developer docs and source codes of Tomcat and find some clues. Would such require modifications of Tomcat source codes: Editing "protected AccessLogElement createAccessLogElement()" to add new pattern items in the switch-case flow for any new field-value pairs, and implement new element class(es) for AccessLogValue. Could you please kindly help to advise? Thank you. Eric
