I would like to be able to monitor how much of the time my system is running throughout the day. What is the best way to log the start and stop times? I would like something that would create a log file so I could see how the run time varies throughout the day. Maybe there is something a lot easier that would just give me a cumulative run time. I could determine the % of run time based on how long it had been accumulating run time.
Anyway, what is the way you guys do it, short of sitting there with a stop watch?
