| - The status monitor ([[backendprocesses#pping|pping]]) monitors basic - but fundamentally important - reachability. Are all the devices alive or are some down? \\ Since NAV has knowledge of topology, root cause in a larger breakdown can also be pinpointed. NAV distinguishes between a device being down or a device being in shadow of a more central device that is down (it is actually [[backendprocesses#eventengine|the event engine]] that is responsible for this correlation). | - The status monitor ([[backendprocesses#pping|pping]]) monitors basic - but fundamentally important - reachability.
