Ah, finally, something I can comment on competently.
The way we do it is we have two pollers and one display. The display does no network testing (we disabled it in hobbitlaunch.cfg) but that's not necessarily required. For your situation, you have to choices.
You use the Net:hostname moniker in your bb-hosts file, andthen you can keep the bb-hosts files synced however you wish (we just scp when we make a change). Any hosts you don't have the Net:hostname tag in will be tested by any servers.
Maintain two separate bb-hosts, with all hosts on the displayservers' copy, but then you have to manually put a noconn tag in the hosts to not ping in the bb-hosts file on the display, otherwise, your display server will be testing those as well, and that status will be over-riding the status from your other server.
Obviously, choice 1 is much easier to maintain, but you will have to put a Net:thing tag in every line of your current script (easy to do with a quick perl script or whatnot. I have one somewhere if you need such). I'd really recommend going that route.

Hi.
If you wish to forward messages using multiple displays you should change a couple of things, revert the configuration files (hobbitlaunch.cfg) to make hobbit act as a display server then you should change hobbitserver.cfg as follows: BBDISP="0.0.0.0" BBDISPLAYS="$BBSERVERIP 12.34.56.78"
The BS ip should be changed to whatever the ip is for your main hobbit server.
This almost works... On my secondary hobbit server I now have it displaying correctly again and there doesn't seem to be any errors on that side. On the main hobbit server I don't see the status for my 64 compute nodes, however they all show up in the ghost clients list. I figured this wasn't a problem as I can just add them to the bb-hosts file. If I do this they always change to red since my main hobbit server tries to query them and cant reach the protected network.
This configuration *should* work. Just reply if it doesn't.
