Hobbit basically reads the hostlist from the bb-hosts file - any host
listed there is included in the report. So if you want a report with
only a select set of hosts, you'll need to generate a special bb-hosts 
file with only those hosts in it.

To use this special bb-hosts file, setup a script to run the report:

   #!/bin/sh

   BBHOSTS=/home/hobbit/server/etc/report-hosts
   export BBHOSTS
   bbgen --reportopts=.....

and run it with "bbcmd myreportscript". You may want to look at the 
hobbitreports.sh script included in Hobbit - it lets you pre-generate
reports on a daily/weekly/monthly basis.

Inside the bb-hosts file, you can then use the REPORTTIME parameter for
each host to define the time-of-day included where outages count in the
SLA calculations that the report provides. If you use the same period
for all hosts, it's probably easiest to define this using a ".default."
host at the top of the bb-hosts file. E.g. 

  0.0.0.0 .default. # REPORTTIME=W:0700:1900

defines the default report-time to be weekdays from 7AM to 7PM. These
parameters and the ".default." hosts are described in the bb-hosts
man-page.
