I now made it with the bbshowhosts command. This command writes a complete
bbhosts file. So I temporarely generate that complete file and then cycle
through all the directories in the rrd directory and grep for each in that
complete bbhosts file. If I not find a host there I drop it.
If there is a nicer solution please tell me.
#!/bin/sh
#
# find old files from components which are no longer in BB-HOSTS
#
. /etc/hobbit/hobbitserver.cfg
echo "BBRRDS: $BBRRDS"
$BBHOME/bin/bbhostshow /etc/hobbit/bb-hosts >hosts.tmp
for i in `ls $BBRRDS`
do
grep $i hosts.tmp >/dev/null
if [ "$?" -ne "0" ]
then
echo "$i found"
# drop the host $i here
fi
done
rm hosts.tmp
Thanks you for your hints.

It seems to me that the cleanest way is to figure out how to make your
inventory system "know" when it is losing something. I agree that it is
easier to write a system that has no memory of what it did in prior runs.
If your inventory system can be queried, or if you have an intermediate
file that can be searched, you might be able to run a "notification"
script from the alert system that would fire on "purple" alarms. What the
script could do is take the host name in the alarm and look for it in your
inventory or other file -- if found, quit. If not found, then the "drop
host" command. This is a kludge, and might cause other issues, but it is
one way to keep your display cleaned up.
Others may have much better ideas!

No. I export the data from our inventory and simply regenerate the bbhosts
files. So old hosts simply are missing in the new bbhosts files. So I
don't know which hosts were deleted. Therefore I would need to store the
old export file and compare it to the new one to find the differences and
use the "drop host" command. I find that very complicated.
Such a cleanup utility would also be helpful if one edits the bbhosts by
hand and forgets to drop a host he has deleted.
I just started to write a shellscript which scans the rrd directory and
tries to find the host in the bbhost files. But is complicated to follow
all the includes. I thought bbhostgrep is the answer but it only can find
a test, not a host.
Any ideas

Are you using the "drop host" function in the "bb" command?

Hi
I have written a script which generates several hobbit bbhosts include
files automaticly from our inventory system. Now I have a problem when a
host has been deinstalled.
I delete the entry from the hobbit config but the old datafiles (rrd and
so on) keep there forever.
Is there a tool to scan the complete hobbit bbhost hierarchy and delete
all data which are not longer needed?
Thank you
Thorsten Erdmann
