I could write start and stop times into a txt file and then automate the calculation of week / monthly uptime...but I´m not a programmer, I cant do a small program by myself, that´s why I asked if there´s some solution that´s already available.
awesomeminer logs the total uptime and you can show the total per month. but ONLY for the payed version of awesomeminer.
the pool logs uptime for each miner, but you can only show charts when your miners are online, you have no addition of the total uptime.
argl...
Use Awesomeminer for example. It is free for 2 PC´s and you can see the mining history. There you can see how many % it mines a day, a week and many more things.
