Internet Services Monitor

Internet Services Monitor (ISM for short) allows you to monitor multiple services running on the Internet. It allows a webmaster to make sure that the web sites are constantly available. It allows a system administrator to probe any TCP port to make sure that critical services such as the Domain Name Service (DNS), Mail servers, and Web servers are responding. Additionally it allows monitoring of URLs to make sure that they contain certain text or that the size returned exceeds some lower bound. For FTP services ISM allows checking for the existance of a file as well to make sure that the size of the file is appropriate. Features a port scanner and even monitors while you're not logged in to windows (also runs as service under NT/2000/XP)
