i'm actually dreading the 0018 release... i've made so many changes to the 0017 oneBash and nvOC in general that moving them to the new version is gonna take forever.. currently working on automatic rig reboot in the event of a system freeze from the miner crashing.
@ tempgoga - I'm curious on your approach, this is next on my plate (without a remote power switch) the easiest - that seems applicable to my setup - is to filter the Genoil watchdog script for a reduced hash rate threshold instead of just 'error' since that script filters stdout from Genoil so technically the info is there to capture already.
I haven't gotten around to this yet but I'm hoping this weekend.
Another idea that I'm thinking of is some sort of port-knocking from a remote machine - it could be enough since the rigs usually are responsive to ssh or local scripts after they "soft crash" with the video cards - but this won't help in case of a complete freeze.
Then you need a remote power cycle ability which is a whole different level of infra.
Cheers!
Sorry for the late response, right now i'm trying to initiate a system reboot in the event that Xorg service takes up 98% or more cpu for for 10 seconds or longer, which happens every time any miner crashes, Xorg always shoots up to 99-100% cpu and stays there, trying to use monit for this, will update if it works.
i like your port-knocking idea.
