Recently I started playing with this backend interface for Nagios called NConf. This is a very young project but from what I see it’s a very promising project:
http://sourceforge.net/projects/nconf/

Since it’s a new project it lacks some features such as, after generating nagios config files, it does not put them into production. So i created a little script that run in cron and check if new configs were created, if yes it put them into the right place and restarts nagios if there are no errors:

Put this code into a new file. Be sure to modify the paths at the beginning with what corresponds with your setup.
do a chmod +x filename on the file

then run crontab -e
and add a silimar line:
*/5 * * * * /path/to/filename

Now every 5 minutes the script will look for new generated configs and put the into nagios. Then checks if there are errors and if there aren’t it restarts nagios.

Nagios is an opensource monitoring system that support custom checks. More info at nagios.org
