The Device.ConnectivityTest.Ping activity allows you to Ping to a selection of devices.
CatTools will Ping each selected Device in turn, and will log any failures to the Report file:
The Ping test is a simple ICMP Echo request, sent from the machine running CatTools to the selected device(s).
It tests the operation of your network between CatTools and the selected device, but only at the IP level. It may or may not be a useful test of your network, or your users' ability to use the network, depending on your specific network design.
The report file provides you with an historical record of the status of the tested devices, which may be useful for later forensic purposes.
