Set:

BBDISP="0.0.0.0"

BBDISPLAYS="ip.address.for.svr1 ip.address.for.svr2"

Note space not commas, and quotes around both. The 0.0.0.0 for BBDISP  
is the marker for multiple servers, and BBDISPLAYS contains the IP's  
for the servers. This is the same for all clients (including the  
~hobbit/client/etc/hobbit on the servers themselves!).

Yes, it will.

Paging, as in notifications? I currently have a different paging rule  
set on the 'backup' box, which just alerts on hobbit server things  
being down, ie:

HOST=myprimaryhobbithost SERVICE=bbd,bbgen,bbtest COLOR=red
         SCRIPT /home/hobbit/bin/sms_notify ADMINS

(Which sends an SMS)

Easiest is to keep the primary hobbit-alerts.cfg handy on the  
secondary box. There might be a better, or more intelligent way. One  
idea I've considered to have some check in the notification script  
that periodically checks, and then just drops notifications if it CAN  
fetch status from the primary host, but sends them if it CAN'T, ie.  
if the primary host is down, the external 'SCRIPT' alert rules kick  
in. See bb(1) manpage, specifically wrt. 'query'. But I really  
haven't given this much thought, and I wouldn't be surprised if  
Henrik or somebody else has a better solution.

Hope that helps,
