I am running Ganglia 3.0.7. Let's say I have a large number of hosts. I've been spending a number of days now trying to get a handle on the precise problem. Ganglia marks hosts down when their TN value creeps over 80 seconds. (Four times their TMAX value, which is hardcoded to 20.) The average TN of the hosts in my gmetad's XML is over 100, and so many of them are marked down. -Kirk ------------------------------------------------------------------------- Check out the new SourceForge.net Marketplace.
