Adding the Loupe Appender for Log4j

Add the following dependency to your pom.xml:

<dependency>
    <groupId>com.onloupe</groupId>
    <artifactId>loupe-log4j-support</artifactId>
    <version><-- desired version --></version>
</dependency>

Configuring the Loupe Appender

Then, modify your Log4J configuration to add the appender to the appenders inventory and register it to a scope of your choosing (root to capture everything). A minimal example is:

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration>
 
   <-- Add this line to add the Loupe appender to Log4j -->
   <appender name="LoupeLog4jAppender" class="com.onloupe.appenders.log4j.LoupeLog4jAppender"/>
 
   <-- This registers Loupe to get DEBUG or higher messages for everything>
   <root>
        <level value="DEBUG" />
        <appender-ref ref="LoupeLog4jAppender" />
   </root>
 
</log4j:configuration>
