Hi Rajinder. It sounds like you are after a monitoring system. There are
a lot of OSS options. I've used Nagios for a lot of years but am
gradually evaluating alternatives.
You'll need another box to check on your website. If a failure occurs it
can alert you through email or SMS.
With Nagios I normally use 15 minute checks per service with Nagios. The
service checks are spread out so a box with 10 services being checked
would actually receive a check every 40 seconds.
It's important to repeat checks several times before declaring a problem
to avoid false positives.
