"Olá" Leonardo, Please note that Nagios uses mostly scripts to check services/disk/etc. and that those scripts that 'tell' nagios the status of the service/daemon/disk/etc. That said, I think you should not focus on Nagios to be proactive hence that it's scripts could be used for that. Let's say you have check_http configured to check www.example.com. It would connect to www.example.com on port 80 and report if it suceeds on sending a cmd or not . If something goes wrong, it would send a critical message back. This does not mean that the script is necessarily alerting nagios about the problem, it is alerting whatever called it in the first place. What I mean is, you don't *need* nagios to be in the middle of it and (IMO) you should not try to integrate it into this kind of solution because it would just make things more complicated. One simple way to implement that would be improving the scripts that comes with nagios-plugins. A "simple" if statement and some coding after it would do the trick. If the script already has the capability to check the status of something and be aware of the present status and take active measures . Interfere with the "function" that prints the message "CRITICAL" to make it, for eg., "ssh -T host /etc/init.d/apache2 restart". This email might be a little confusing cause I'm not thinking proper english this morning, but I would be happy to help you in our both mother language (portuguese) if you prefer. Good luck for now,

I have a very small setup (2 linux server being monitored via npre by a third linux server) and i'd wrote some bash scripts to monitor some of the services that we run on those services (proprietary services, non-standard ones like ssh, apache and that stuff).I know Nagios can send sms, email and other things to warn administrators about problems, but can Nagios take any action to fix the problem, like restart the service if reach critical state, or restart the service if the service stays critical for more than 5 minutes? If yes, can someone just point me to the direction i should go? :) Tks in advance, and sorry about my poor english. I'm from Brazil. |
