| - | * [[backendprocesses#the_status_monitor_pping|The status monitor]] monitors basic (and fundamentally important) reachability. Are the devices alive? Since NAV has knowledge of topology, NAV can pinpoint root cause in the case of a larger breakdown. This is done by distinguishing between a device being down or a device being in shadow of a more central device that is down. | + | 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 tool. The four monitors are: |
| - | * [[backendprocesses#the_service_monitor_servicemon|The service monitor]] monitors services. A number of services are supported (ssh, http, ssl, imap, pop3, smtp, dns, rpc, samba, dc and more). | + | |
| - | * The module monitor (within [[backendprocesses#getdevicedata|gDD]]) monitors the operations of modules within a switch stack or within a chassis. | + | |
| - | * [[backendprocesses#the_threshold_monitor_thresholdmon|The threshold monitor]] monitors the RRD data and send alarms if a threshold on a given value is exceeded. | + | - 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). |
