I was thinking the other day it would be nice if we could set performance notifications, like idle notifications. So If I have a 1000GH miner, I could set it to report if it falls below 920 for more than 30 minutes.
I had an S2 module turned off (100GH) for more than a week before I noticed it, due to the variation of other reported miner speeds.
make every miner its own worker
if you have a situation like a KNC jupiter that drops its OC then you have to make something on your end watching that performance drop
