The integration and configuration in a web.xml file works as follows:

 
  <web-app>
  ...

 <context-param>
  <param-name>GCServletContextListener.samplingIntervalSeconds</param-name>
  <param-value>15</param-value>
 </context-param>

  <context-param>
   <param-name>GCServletContextListener.initialSamplingDelaySeconds</param-name>
  <param-value>0</param-value>
 </context-param>

 <listener>
   <listener-class>
     kieker.monitoring.probe.servlet.GCServletContextListener
   </listener-class>
 </listener>

 ...
 </web-app>
 }
