Is there any way to get the list of currently logged in users in the system? Log

did the solution that Eduardo provide not work on this post
forum.appian.com/.../e-112708

Here the use case is different, I want to see the number of users who are logged in into the production system at the moment. that post was about how to get the service context for the logged in user!

this post addresses that.
forum.appian.com/.../e-103367 It basically states that you need to use features of the app server to achieve that but does not give details

Used JBoss's JConsole to get the active-sessions using the command-> /deployment=suite.ear/subdeployment=web.war/subsystem=web/:read-attribute(name=active-sessions). But I am not sure it returned the right number of active sessions.

i am using Application server and considering the active session count as number of logged in users. it is leading to a false assumption because if the user closes the window the session would still be alive on the server until the session reaches "session-max-alive-time" period.To achieve this can we implement SessionListeners in any way to get the actual count of logged in users?

Quick dirty solution (or may be not) -> Go back to java -> write a Session Listener like below:

public void sessionCreated(HttpSessionEvent se) {
//Creating new session...
activeSessions += 1;
SessionCounterDao.getInstance().pushActiveSessionToDB(se.getSession());
System.out.println("New session Created..." + se.getSession().getId());

}

public void sessionDestroyed(HttpSessionEvent se) {

System.out.print("Destroying... " + se.getSession().getId());
SessionCounterDao.getInstance().popDestroyedSessionFromDB(se.getSession());
if (activeSessions > 0) {
activeSessions -= 1;
}
System.out.println(" --> Destroyed");

}

You have now SPRING_SECURITY_CONTEXT there

String springSecContext = (String)session.getAttribute("SPRING_SECURITY_CONTEXT"); /* geeting all sesision info here */

Enjoy!!

Thanks Ritesh! does this work like an appian plugin? or do we need to configure this plugin anywhere else?

No, It is not aplugin. it is a basic "Session Listener" for appain, nothing else. will update your db with user's sessions with all required information i.e. session creation + last access time + destroy time and additionally SPRING_SECURITY_CONTEXT value. So, now use this table as base table, do some Java + DB excecise, develop some appian user reporting applciation and thats it.

If this "SessionListener" class does not need to be deployed into Appian, after developing a SessionListener how can we make it listen to the Appian's session events? do we put it outside appian? or how?

no, that has to be there in classpath + web.xml listener entry + jboss node(s) restart.
