AppManager provides a simple way to determine whether the computers in a cluster are up or down: the General_PingMachine Knowledge Script. Located on the General tab, which is available in the Master and NT views of the Operator Console, the General_PingMachine Knowledge Script checks the availability of computers that respond to ICMP Echo requests.
In the List of computers to check parameter, type a comma-separated list of the computers for which you want to check availability. You can also use the Full path to file with list of computers parameter to specify the location of a file that contains a list of the computers you want to check. For more information, see the Help for the General_PingMachine Knowledge Script.
