<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">

<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/" debug="false">

<appender name="FILE" class="org.apache.log4j.RollingFileAppender">

<param name="File" value="<WEB_SERVER_HOME>/logs/SentinelWebDashboard.log"/>

<layout class="org.apache.log4j.PatternLayout">
