access 로그 설정
Tomcat 사용 시 Access Log를 기록하는 방법은 다음과 같습니다.
$CATALINA_HOME/conf/server.xml 파일 내용 중 아래 부분의 주석을 제거하신 후 Tomcat을 재 시작하시면 됩니다.
<!--
<Valve className="org.apache.catalina.valves.AccessLogValve"
directory="logs" prefix="localhost_access_log." suffix=".txt"
pattern="common" resolveHosts="false"/>
-->
<Valve className="org.apache.catalina.valves.AccessLogValve"
directory="/apps/atlassian/logs" prefix="" suffix=".tomcat2_access.log"
pattern="%t %a %Ts %{userid}r %B %U%q"
fileDateFormat="yyyy-MM-dd"
resolveHosts="false"/>
