SiteMonitor is a tool to monitor your Web sites and notify you when they are down. SiteMonitor will check at fixed timed intervals that your Web site is still functioning correctly. It will also log activity to a log file for future reference. This is the no. 1 tool a Web administrator needs. You can use SiteMonitor not only to monitor your website but also servers which have a Web Interface such as Microsoft Exchange Servers, and other mail servers.
