How i can check the number of user using the system at anytime .
in other word i want to know how many user is online :)
If you want to know the number of people on Roundcube you could try querying the Roundcube session table. If you want something fancier you could add some sort of analytics software.
thanks for your answer but another question about the session table
but is the user do not log out and just close the tab the session closed or what ??
Sessions are still in the database if someone doesn't logout but you can check the date/time the session was last changed to get a better idea if its still active. Again if you want something more precise you should looking to adding analytics software.
Thanks a lot for ur answers :)
