Since it is reasonably generic, it should be suitable for many different UNIXs.
The program's purpose is to monitor the components that make up a UNIX server. For example, your UNIX server functions as a whole due to components like sendmail, inetd, named and httpd servers.
At a user-specified time interval, a configuration file containing the server daemons that you want to monitor is scanned. If one is found to be missing, an e-mail is sent to your support team.
If Hylafax or another paging system is in use, the e-mail could be redirected to page your support team as well.
