If you can't keep it all in your head then you could type it in a file. But sounds like you may need another manager or lead or two to help with tracking success. The other thing you can do is track team success based on project. You would not want to use metrics but rather knowledge of the actual effectiveness of the programmer. Evaluating this requires someone with programming knowledge who can see first-hand what their code is and what they accomplish on the project. Again look at the work output rather than your guesses about their hours. If they are accomplishing their tasks then they are not slacking off. If they are not accomplishing their tasks, make sure they have motivating work and autonomy. Having covered all of the above, the next step if you really have a problem is a serious warning and probably just firing them if/when they don't radically change their behavior which is somewhat unlikely to occur.
