# After Installation

## Demonstration views

NagVis contains several demo maps on initial installation. There is also a rotation defined to give you an example of the features of NagVis. Certainly Nagvis has a lot more features than we can show you with this demo configurations. So you should read the documentation and be creative.

If you are familiar with NagVis you can delete these demonstration maps and rotation without problems.

## Configuration Files

NagVis is based on several configuration files. The main configuration file stores the basic and global configuration options. The map specific configuration options are stored in map configuration files. A special type of maps are the automaps, the automaps have an own configuration file directory. The automap configuration files use the same syntax as the map configuration files but have some more options.

The whole NagVis configuration can be changed using the webbased configuration program called WUI.

## Authentication/Authorisation

By default NagVis uses an internal user and permission database (SQLite) for handling authentication and authorisation. Nagvis uses a role based permission system. After installation there are two default users defined:

- Username: nagiosadmin, Password: nagiosadmin
- Username: guest, Password: guest

The following roles with these permissions are available:

- Administrators: Full permissions on the whole installation
- Users: Read access to all maps, automaps and rotations in the installation
- Guests: Read access to all demo maps, automaps and rotations

These default users and roles should be ok for beginning. You may delete these users and roles but please be aware not to delete the last administrative user.
