NAV has a number of background processes that monitors the operational status of the network:
The status tool gives an overview of all the active alarms. The display is divided into several sections, this is per-user configurable using the preferences tool from the tool bar. The default sections include:
In addition using the preferences tool (reached from the NAV bar) you may add:
For each section the NAV user may also choose to filter out certain alarms based on either organization, category (GW/GSW/SW/SRV etc) or state (up/down/shadow).
From each status page section a link to history is provided. You may also see individual histories using the link provided on each line in the listing. The history view goes per default 7 days back, but can be increased to a maximum of 30 days.
For the services section you may in addition go to a matrix view that shows red and green lights for all monitored services.
For the webfront - none. But the data the status page uses is supplied from backend processes such as pping, servicemon, etc. They have config files that can alter their behavior, for details see backendprocesses.
