Capture Log4j2 Data with Loupe

Loupe was designed to be the best way to process and view Log4j data available; capturing everything you’re already sending to Log4j2 and extending it with Loupe’s additional data.

How the Loupe Agent works with Log4j

Loupe provides an appender package for Log4j and Log4j2. This works beside any existing appenders you have registered so you can try Loupe in parallel with your existing log storage techniques. To add the appender to your project, just add Loupe to your pom.xml:

<dependency>
    <groupId>com.onloupe</groupId>
    <artifactId>loupe-log4j2-support</artifactId>
    <version><-- desired version --></version>
</dependency>

The Loupe Agent and its appenders are in the Maven Central Repository so you can easily add them via Maven or your favorite package manager.

To quickly start capturing your log data with Loupe, following our getting started guide.

Centralized Logging, Error Management, and More

By adding Loupe with your existing application, all of the custom messages you’ve created will be merged with the additional data Loupe captures and can be viewed locally or sent to a Loupe Server for centralized storage and analysis.

Within minutes you can be getting notifications of each unique error reported in your application, with all the tools you need to manage those issues and support your users.
