[Xymon] Additional tests from xymon server

[Ioan Damian]

Hi

Thank you all for your replies. xymongrep is what I was looking for. 
Also, Buchan's script was very helpful.

I've managed to add the desired checks by adding a new task in 
$XYMONHOME/servers/etc/tasks.d/domain-checks.cfg like this:
[Domain]
         ENVFILE $XYMONSERVERROOT/server/etc/xymonserver.cfg
         NEEDS xymond
         CMD $XYMONSERVERROOT/server/ext/domain_check.pl
         LOGFILE $XYMONSERVERLOGS/ext-domain_check.log
         INTERVAL 5m

In $XYMONSERVERROOT/server/ext/domain_check.pl I used xymongrep to 
filter out only the hosts with the domain tag in hosts.cfg and sent the 
status for each of the hostnames I've found back to xymon.

I'm a bit suprised I couldn't find documentation for such endevours more 
easily.
