Simple end-user tracking for Java EE web applications.

Servlet-Filter is an implementation of Java EE HTTP Servlet Filter. This servlet filter tracks the following:

• End-user performance, behavior
• HTTP request performance, errors, exceptions
• HTTP header, request parameters and attributes
• JVM context such as CPU, memory, GC

The output can be streamed to any of the TNT4J sinks: file, log4j, socket, visual analysis using jKoolCloud.

Simply add the following to your application's web.xml:

<filter>
	<filter-name>ServletFilter</filter-name>
	<filter-class>com.jkoolcloud.tnt4j.servlet.filter.TrackingFilter</filter-class>
</filter>
<filter-mapping>
	<filter-name>ServletFilter</filter-name>
	<url-pattern>/*</url-pattern>
</filter-mapping>
<context-param>
	<param-name>op-level</param-name>
	<param-value>DEBUG</param-value>
</context-param>

NOTE: Make sure all jar files required by ServletFilter are in your application's classpath.

Servlet-Filter requires the following:

• JDK 1.8+
• TNT4J (https://github.com/Nastel/TNT4J)
