Strange... Today's morning cgminer dead. All cards have status OFF. Rig was rebooted, but it didn't help - when i start mine all cards sets to OFF. Cgminer with the same config for dogehouse was started and all works correctly. Very strange. Will try to investigate this issue today's evening
You should probably look into CGWatcher. I'd guesstimate its value to a 5MH/s farm at about $50/mo, and it's free. CGRemote's awesome, too, but actually costs (a negligible amount of) money.
CG Remote is great, especially the latest version which sends me an email every time a miner goes down. It's impossible to monitor dozens and dozens of computers without it!
