Open the Mac App Store to buy and download apps.
Knock Knock is a network utility application living in your Mac OS X menu bar. It automatically checks the reachability of your network hosts on a regular basis. If there is a webserver running, Knock Knock is able to check the HTTP status response code for you as well.
*Stay up to date at all times*
Knock Knock provides a panel that stays on top of your other apps for an easy overview if any host is no longer available or comes back online.
It has never been so easy to keep taps on all of your domains, servers or even computers in your local network! Just enter a hostname or IP address, set the time between reachability checks and relax.
*Sky's the limit*
Check an unlimited amount of sites as often as you want and be the first to know when something is wrong - with your own sites or any other site on the web.
Make sure your websites return a status code greater than 400 if there are unexpected errors with your code, like timeouts or "unable to connect to database".
