I notice that one of my sites wasnt working properly and was giving me 500 errors. Nagios didn't catch it because the HTTP server was still working.
Is there a way i can tell nagios to check the health of my site? I think i'll just write a script which pings certain pages and make a cronjob for it. On error i'd get an email so thats my suitable replacement for the moment will be.
I am running debian linux
