Widget Watch: WatchMouse
Today's widget is a Dashboard widget from WatchMouse called...well...Watchmouse. Enter your website's information, and the WatchMouse widget will display your site's availability statistics over the preceeding 72 hours. It also checks your site for issues every five minutes, and beeps an alert after two consecutive errors have been found.
The widget was originally written to compliment WatchMouse hosted websites, but will work just as well with your own personal or business site.
