Tomcat 6 User Connected

[Hoa Doan <ge...@yahoo.com>]

How do you find out how many user are connected to the server?  Do you get a thread count? if so how do you do that?

Tomcat Manager shows the number of Sessions per site, I think it
includes both the number of browser and bots connected to the site.

You might want to consider a Javascript based solution to track only browsers.

By definition HTTP is connectionless, so there isnt really a true user 
count.
A user reading, is busy but not in the server.
If you want to monitor all users you need to use cookies.

If you want to monitor concurrent users, then you could have a little thread 
safe routine at the start and end of your processeing routine that 
increments and decrements.
Need to make sure the counter is thread safe.

or you could use HttpSessionListener (your Thread count as you call it)
and set up a counter

These techniques are good for internal monitoring... when servlet needs to 
know how busy it is.

For server wide stuff I think you would have to build a filter that watches 
every request... could watch sessions, server contexts etc.
If you google for Tomcat Monitoring you will find many tools built on this 
principle and do it yourself code...

Have fun....

Fairly certain the datasource and connection information you're looking for 
is implemented in Lambda
