 +===== Back-end processes ===== 
 + 
 +NAV has four background processes that monitors ​the operational status ​of the network. It is the events triggered from these monitors that are displayed in the status toolThe four monitors are: 
 + 
 + 
 +  - 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 service monitor ([[backendprocesses#​servicemon|servicemon]]) monitors services. A number of services are supported (ssh, http, ssl, imap, pop3, smtp, dns, rpc, samba, dc and more). 
 +  - The module monitor (modulemon within [[backendprocesses#​ipdevpoll|ipdevpoll]]) monitors the operations of modules within a switch stack or within a chassis. 
 +  - The threshold monitor ([[backendprocesses#​thresholdmon|thresholdmon]]) monitors the RRD data and send alarms if a threshold on a given value is exceeded. 
 + 
 +For more information on the event and alarm system, see [[eventandalertsystem|here]].
