Hi Kent,

thanks for the kind words - I'm glad you like Hobbit.

"Disable" has the special meaning of "making the status blue", but I 
get the impression that is not what you want - you'd like to remove it
altogether from the display.

The current release- and beta-versions will not let you do that, but
I've just committed a change so you can remove any of the columns from
the client-side tests through a new tag in the bb-hosts entry. E.g. if
you want to avoid having a "msgs" status for the host foo.bar.com, then
the entry in bb-hosts would be

   10.0.0.1 foo.bar.com  # NOCOLUMNS:msgs

You're not alone. The safe thing to do is to start out with the default
setup and just copy your bb-hosts file over from Big Brother - the
default setup should give you just about the same setup as you have in
BB. Then you can begin playing with all of the fancy new stuff.

I'd recommend settling down with a cup of coffee, and browse through
some of the man-pages. They're all available on-line through the "Help"
menu in your Hobbit installation, and they should cover all of the 
configuration files and tools.

Basically, you have two ways of doing that.

1) Add some extra pages to your normal Hobbit display. You just add them
   to the bb-hosts file and list the hosts you want on those pages, but
   instead of copying the entire configuration entry for a host, you
   just add it with an IP of "0.0.0.0" and a "noconn" tag. E.g.

       page sun Sun servers
       10.0.0.1  www.foo.com  # http://www.foo.com/
       10.0.0.2  dns.foo.com  # dns
       10.1.0.1  wwwtest.foo.com # http://wwwtest.foo.com/

       page prodservers Production systems
       0.0.0.0   www.foo.com  # noconn
       0.0.0.0   dns.foo.com  # noconn

       page testservers Test systems
       0.0.0.0   wwwtest.foo.com # noconn

   When a host is defined twice in the bb-hosts file like this, the
   second definition is merely a "place-holder" for the webpages. All
   of the network tests and the other definitions are taken from the
   primary definition.

   This gives you one set of webpages, with sub-pages for the various
   groupings you'd like.


2) If you want to isolate the groupings completely, then you can use
   the "Alternate pageset" method, where you generate multiple sets
   of webpages, with selected hosts going on different webpages.
   See the "Building alternate pagesets" description in the bbgen(1)
   man-page.

It should work in the current beta, but the documentation link from the
Help menu is missing the screenshots. They are included in the menu
on my site, at http://www.hswn.dk/hobbit/help/criticalsystems.html

Which browser are you using ? The link you're clicking sends back data
with a content-type of "text/plain" - some browsers (e.g. Konqueror
from the KDE project) will not display this inside the browser, but
prefers to download the file and bring up an external editor to display
it. It might be possible to alter this behaviour through a configuration
setting in your browser (in Konqueror, you do it via the Setup -> 
File associations menu - tell it to use the embedded viewer).
