On my server I'm keeping track of stats extensively using SQLite. Anything from general kill count to damage dealt with a specific weapon or class is being stored. Not only will it help me balance the server, but the stats tie in with achievement, leader-board, and unlock systems.

I can easily pick out which class is being used the most, how it compares to other classes based on averages, and also spot outliers to catch hackers, bug abuse, etc without relying on players to report the problem.

I'm not sure what the OP is really asking for, but the way I'm doing it is very simple because SQLite pretty much does everything for me. All I have to do is keep an organized database, and call a function to increase the values.
