For monitoring the Web server performance the Web Server Manager portlet is available by selecting Web Server on the Console Navigation menu on the left hand side. Currently, this feature is only supported on the Jetty distribution of Apache Geronimo. By default this portlet is not enabled, click on the enable button to start collecting statistics.
Once enable you will start collecting information on the number of requests, concurrent connections, requests duration, etc. The following figure illustrates all the values being collected.
The three links at the bottom let you refresh the current statistics, disable the portlet and stopping the collection of new data and reset the data collected.
Note that any request from you via the Geronimo Administration Console (for example refreshing statistics) will be also reflected in this data collection.
