 Enumeration em = (Enumeration)session.getAttributeNames();
    while(em.hasMoreElements()){
         String name = (String)em.nextElement();
         session.getAttribute(name)
         }

you can use the HttpSessionListener interface to achieve that.

Sample code that does just that (and more) can be found at http://www.javaperformancetuning.com/tools/jamon/#SampleCode. JAMon is an easy to use (a start() and stop() method) API that measures performance, scalability and counts "things" in general. For example in your case you could count sessions.
