Application Performance Web Sequence Chart

The Web Sequence Chart as shown in the screenshot on the right displays measurements of our Python CDDB example. The sequence diagram shows a complete calling sequence starting with a request in the HTTP server and ending in several requests for fetching track information for CDs.
