I believe a "ghost" is where there is data/history for a host but it is
not listed on bb-hosts.

I thought "ghosts" were clients that send in data, but their name is
not a match in the bb-hosts file. If you decide to get rid of a client, you
have to a) update bb-hosts to suspend polling, and b) update the client so
either the agent does not run, or so that it sends its data elsewhere.
In my case. I was fooling around with the bb-stocks.sh script from
deadcat.net, running it from hobbitlaunch.cfg on the server. It sends
reports where the hostname is the ticker symbol (e.g. IBM, MSFT, etc) and
the column name is "stock". I let it run for a while, then marked the entry
in hobbitlaunch as DISABLED and dropped the stock names.
This morning, while reading this email thread, I went back to the script
and inserted "exit" right at the top, so it shouldn't be possible for the
script to produce a report, even if it gets launched.
The ticker symbols do *not* show up in the hobbitdboard output. They
*were* in the data/hist/allevents file, but
trimhistory --cutoff=`date +%s --date="19 May 2008"` --drop
took care of that. I've confirmed via grep that the names do not appear in
any file in the Hobbit directory hierarchy.
I *do* still see the ticker symbols in "bb localhost ghostlist", but they
don't appear in the Ghost Clients web page.
Maybe I'm missing something obvious. Here's a quick test if you're
interested in replicating the problem:
server/bin/bb localhost "status server,domain,com.bogus green `date`"
server/bin/bb localhost hobbitdboard | grep server
server/bin/bb localhost ghostlist | grep server
server.domain.com should not ever have existed in your bb-hosts file. It
will show up in the Ghost Clients web page for 5 minutes. 45 minutes after
doing the above, it's still showing in "bb localhost ghostlist".
