Session Monitoring tool?
Folks;
does anyone know of any tomcat tool to watch HTTP sessions which
are active in any deployed web application (and, best case, data
assigned to them, aside the session ID itself)? I thought /manager
or /admin to provide functionality like this but so far I failed to
find it...
Thanks in advance and bye,
Kristian

You may want to implement your own HTTPSessionListener for your servlet. It
looks something like this:
package mypackage;
import javax.servlet.http.HttpSessionListener;
import javax.servlet.http.HttpSessionEvent;
public class SessionListener implements HttpSessionListener {
static int activeSessions = 0;
static int maxActiveSessions = 0;
/** Session Creation Event */
public void sessionCreated( HttpSessionEvent se) {
synchronized (this) {
activeSessions++;
if (activeSessions > maxActiveSessions) {
maxActiveSessions = activeSessions;
}
}
}
/** Session Invalidation Event */
public void sessionDestroyed( HttpSessionEvent se) {
synchronized(this) {
if(activeSessions > 0) {
activeSessions--;
}
}
}
/** get the number of currently active HTTP sessions */
public static int getActiveSessions() {
return activeSessions;
}
/** get the maximum active concurrent HTTP sessions used so far */
public static int getMaxActiveSessions() {
return maxActiveSessions;
}
}
In your web.xml, add the following lines to make sure Tomcat sends the
events to your session listener during runtime:
<!-- Listeners -->
<listener>
<listener-class>mypackage.SessionListener</listener-class>
</listener>
Hope this helps.

What kind of information are you looking for?
If it's application specific data, it wouldn't be difficult to write
something yourself.
I have a sample app that shows the users logged in to the system, how
long they've been active, when the session times out, and what the last
page they've hit is.
See: http://simple.souther.us/not-so-simple.html
Look for SessionMonitor.

Thanks a lot for the pointers; I'll check out the both and see what

Lambda Probe displays more information than Tomcat's manager app, but I
don't know if it's sufficient for your needs. Get it at:
http://lambdaprobe.org/
I have no affiliation with the above product - just a satisfied user of
it.
You should also take a look at MoSKito; lots of very detailed
information collected and displayed by it:

Yes, there is, but the information it provides is rather limited (to
telling me how many active sessions there are and what session timeout
is set)...
Cheers,
Kristian

Hmm correct me if i'm wrong, but isn't there's a 'Session' Column in the
manager list page where the active session of each web application would be
displayed?
Thanx.
