I dont quite understand what you mean. Are you referring to the statistics on the "hobbitd" column status page ?
Jip.
All three are running the hobbitd, because of failover. If the connection between two server fails or the "main"-server fails, I have a hobbitd left. But not all hobbits are running all network-tests.If you have three hobbit servers running, I assume one of them runs the hobbitd server, and the others are just doing network tests. It's only the one that runs the hobbitd daemon where it makes sense to have hobbitd statistics.
