I am looking for a tool that can help me monitor the availability of my website.
Basically, I should input my website URL to the tool and it should monitor whether the site is up and send the feedback to my email. It should equally hang on the status menu (indicators).
I have done some research. I came across monitorix,nagios,... but they all are not that light.
Does such a tool exists, if so can I have their links?
