This is still quite confusing to me too and I have not investigated much. I thought an interval less than dmax would keep the host alive, but with dmax=600 and a period of 300s, I sometimes found the hosts "down" for Ganglia. With 60s period, all seems ok, so where important I'm using 60s for now. Never found time to dig in the actual code, so if you figure it out better, I'd like to know it too. >> PS if it's an APC, see the attachment, courtesy of a work colleague. > yes, it is APC.
