Here's another method that uses the 400 ping command and allows you to account for sometime hic-ups in system...
Program reads file Yourlib/YourFile. Yourlib/Yourfile contains the host names of the servers/machines to be monitored. Any additions or removals of hardware need to be reflected in Yourlib/Yourfile. Using Yourfile and the system host table program will ping all servers listed. If the server responds to one or more ping out of five, system will issue a pass status. If the server fails all five requests, a message/page/escape can be sent. This eliminates needless pages on servers that may not respond due to heavy workloads at peak periods.
