We are currently setup with distributed polling with a master LiberNMS and then a probe at each campus using rrdcached.
It has been working flawless until around this time (Oct 31’ish).
I didn’t realize we are on the dev (daily) fork and around the same time ALL of our devices showed down across 7 colleges.
Now all of our devices randomly show down/up through out the day.
Is there a way to force a cut over to stable?
