I didn’t know that my site was not running. And it is hard to monitor as well. But now after few hours of hard work and some help from the site here http://www.labnol.org/internet/website-uptime-monitor/21060/ it was real life saver. Although it was initially different to configure but now I am getting my emails when site goes down and not configured.
So now on I will try to make more and more post if possible.
