This is an old revision of the document!
Network Administration Visualized can be divided into two parts: A set of back-end processes and a web-based user interface. The back-end processes are responsible for collecting and analyzing data from your monitored equipment and for performing various background maintenance and administrative tasks. The web-based user interface's main task is to present the collected and analyzed information to the network administrators and other users, and also to allow the administrators to perform administrative tasks such as editing the list of monitored equipment, control other users' access to the web interface, set up maintenance tasks, post operational messages and so forth.
Although you may distinguish between an administrator and a user, this document is about using NAV; the network administrator(s) will usually also be the NAV administrator(s), and so will also be a NAV user in this context.
The main index page of the web interface displays a set of configurable links and contact information, a configurable welcome message, the latest operational messages (if any), and a shortlist of the current status of your devices (i.e. it lists devices that are down).
The configuration files for the various configurable information bits above are located in the webfront
configuration subdirectory.
Config file | Purpose |
---|---|
welcome-anonymous.txt | The welcome message displayed to anyone who is not logged in |
welcome-registered.txt | The welcome message displayed to logged in users |
contact-information.txt | Displayed in the contact information box |
external-links.txt | Displayed in the external links box |
nav-links.conf | Internal links to your NAV system, displayed to everyone who has access to the particular URLs |
Despite the dubious .txt
extension on most of these files, HTML can be used in them. nav-links.conf
has its own special format.
The top part of each page contains the NAV logo and a navigation bar. The links displayed on the navigation bar are configurable per user account, by selecting the *Preferences* link.
The web interface is divided into several tools, which can be found on the toolbox page. The default navigation bar contains a link to the toolbox. Most users who have been using NAV for a while will configure their navigation bars with direct links to their preferred tools, so that they can be reached from anywhere within the web interface.
These are the available tools as of NAV 3.2:
Tool | Description |
---|---|
Edit database | Manual entry of data into the NAV database. Most importantly, this is where you specify what IP devices to monitor . This will be the first tool to use after having installed NAV |
