Hi,

  We want to know how much "users" (persons with browser and aplication URL, ) more or less are connected to our systems and we don't want to use ITCAM or commercial products for that purpouse (if they are cheap and easy to use yes of course ;-).   For that we have done and jmx/pmi program to obtain this information.  

  We have obtained diferent information about the applications using web application counters
  publib.boulder.ibm.com/infocenter/wasinf...

  With requestcount we obtain the hits on the application but not the "users", one call to the application can do multiple hits.
 
  Using Servlet Session counters:
  publib.boulder.ibm.com/infocenter/wasinf...

  With LiveCount we don't see any sessión created when we invoke snoop servlet (without security), so we are understanding that if the application doesn't store anything in the session object (or if the security of the application is off) there is no "hit" in the counter.  


  is this so? are wrong?

  how can we know the number of "users" connected to our application servers?

  any ideas are appreciatted  



Thanks in advanced,  Regards

Request count will give you requests process by that servlet. When the application is 'snoop' or the requests gets processed very fast then it is very difficult to see them in the live count/sessions. 

If you are using a web server [apache or IHS] infront of the application server and would like to see how many reqests are coming to a url/server, you can consider configuring 'server-status' at web server level.

Check this open source monitoring tool : Java Melody, this involves adding few jar files to the application and modifying web.xml file. 

Thanks Joseph,

  but one thing are the request an other sessions no? what we want to know is more or less the users and with request we know the "hits" at the application level.

  When we use the sessions we see that the user need to do or "login" or the application need to store something in the session object, that is our cuestion? isn't session in applications without security or if nothing is store in session objet?

  I know the server-status module but at the web server level is posible estimate the number or users based on the threads in use? the "problem" with threads at the WAS level is that they are very efficient and one thread could serve more that one request.

 We have seen that there is in WAS an "http request trace" and we are studing how to use it.

   I'll try the software you say, thank you very much!!!!

Have you looked at IBM ISA Lite which is free

Hi Tony,


  I know the ISA workbench and some of it's tools for debug memory problems or trace log i use it

  With the ISA Lite is some tool to determine the "users" conected?

 Thank in advanced
