Most important thing is:
i need to know how many persons (unique too) are connected to server per month/few mothn not matter.
Is it possible to know which user name connected most times, or was in that server most time online, EDIT: log chat, and something like that..

Is there any statistics programs that i can add or look at?
Thnx in advance!

You can do that using InSim.

Maybe there is made an app' like this?
