The Main Configuration file is designed in plain text "ini"-like format.
There are sections which are marked by the surrounding brackets [] and variables which have an assigned value. The variables have to be in the correct section so you have to ensure to have uncommented the section too.
Semicolons (;) are used to mark comments. Sections and variables with a leading semicolon are commented out and won't be recognised by NagVis.
In a fresh NagVis installation there is no file with the default configuration. The default configuration is stored in the PHP-Code of NagVis. If there is a file etc/nagvis.ini.php which has stored configuration information it will override the default configurations.
There is a file etc/nagvis.ini.php-sample with sample configuration values. All values are commented out.
All values which are used througout NagVis are stored in the global section.
| Value | Default | Description |
|---|---|---|
| audit_log | 1 | Enable/Disable logging of security related user actions in Nagvis. For example user logins and logouts are logged in var/nagvis-audit.log. |
| authmodule | CoreAuthModSQLite | Defines the authentication module to use. By default NagVis uses the built-in SQLite authentication module. On delivery there is no other authentication module available. It is possible to add own authentication modules for supporting other authentication mechanism. For details have a look at the authentication module documentation. |
| authorisationmodule | CoreAuthorisationModSQLite | Defines the authorisation module to use. By default NagVis uses the built-in SQLite authorisation module. On delivery there is no other authorisation module available. It is possible to add own authorisation modules for supporting other authorisation mechanism. For details have a look at the authorisation module documentation. |
| controls_size (new in 1.6) | 10 | The size (in pixels) of object controls in unlocked (edit) mode in the frontend. Object controls are for example the modify, delete and move icons. |
| dateformat | Y-m-d H:i:s | The format of date and time shown in NagVis. Available options like in date function of php |
| language | en_US | Select default language to use in NagVis. There are several translations delivered by default: en_US (English), de_DE (German), fr_FR (French) and pt_BR (Brazilian Portuguese; since 1.4.4). Since NagVis 1.4 you have to select the languages in a new format ("en_US" instead of "english") |
| language_available | de_DE,en_US,es_ES,fr_FR,pt_BR | You may want to give your users a limited number of languages to choose from. You can control the behaviour without deleting the language files from your NagVis installation. If this value is left empty NagVis will fallback to all configured in languages. If you like to add a new language to your NagVis installation you need to add it to the list here. |
| language_detection | user,session,browser,config | This controls how NagVis tries to detect the language of the user to translate NagVis. NagVis knows several mechanisms to detect the language: - user: Explict user selected language - session: When the user selects a language it is stored in the current session - browser: NagVis tries to detect the user language by the browser agent - config: The installation default language The order you set the options determines how NagVis uses the different mechanisms. |
| logonmodule | LogonMixed | Defines the logon module to use. By default NagVis uses the mixed auth module which trusts the username given in REMOTE_USER or displays a HTML logon dialog for requesting authentication information from the user when REMOTE_USER is not set. On delivery there are the following modules available: LogonMixed: The mixed logon module uses the LogonEnv module as default and the LogonDialog module as fallback when LogonEnv returns no username. This should fit the requirements of most environments. LogonDialog: This is an HTML logon dialog for requesting authentication information from the user. LogonEnv: It is possible to realise a fully "trusted" authentication mechanism like all previous NagVis versions used it before. This way the user is not really authenticated with NagVis. NagVis trusts the provided username implicitly. NagVis uses the configured environment variable to identify the user. You can add several authentication mechanisms to your webserver, starting from the basic authentication used by Nagios (.htaccess) to single sign-on environments. Simply set logonmodule to "LogonEnv", put the environment variable to use as username to the option logonenvvar and tell the authentication module to create users in the database when provided users does not exist. The option logonenvcreaterole tells the module to assign the new user to a specific role set to empty string to disable that behaviour. LogonMultisite: This module uses the authentication provided by auth_* cookies which have been generated by Check_MK multisite when using the cookie based authentication. It is possible to add own logon modules for serving other dialogs. For details take a look at the logon module documentation. |
| logonenvvar | REMOTE_USER | Defines the environment variable to be used for fetching the authenticated user from the webservers environment. This option is only used with the logon modules LogonEnv and LogonMixed. |
| logonenvcreateuser | 1 | Tells the LogonEnv/LogonMixed module to create a user account for each unknown user which opens the NagVis pages. This option is only used with the logon modules LogonEnv and LogonMixed. |
| logonenvcreaterole | Guests | Tells the LogonEnv/LogonMixed module to create the user accounts with the given role associated. This option is only used with the logon modules LogonEnv and LogonMixed. |
| logon_multisite_htpasswd | The path to the htpasswd file which is used by multisite. Only used by the LogonMultisite module. | |
| logon_multisite_secret | The path to the auth secret file which is used by multisite. Only used by the LogonMultisite module. | |
| logon_multisite_createuser | 1 | Same as the above "logonenvcreateuser" option. Only used by the LogonMultisite module. |
| logon_multisite_createrole | Guest | Same as the above "logonenvcreaterole" option. Only used by the LogonMultisite module. |
| refreshtime | 60 | Refresh time of maps or reloading the next map in map rotation |
| sesscookiedomain | auto-detect | You may need to control for which domain NagVis will store the session cookie. By default NagVis tries to auto detect this option value by using the webservers environment variables. This should work in most environments but may be changed e.g. when using url rewriting. |
| sesscookiepath | auto-detected | You may need to control the path on which the cookie will be set. By default NagVis uses the paths/htmlbase value for setting the cookie. This should work in most environments but may be changed e.g. when using url rewriting. |
| sesscookieduration | 86400 | Lifetime of the NagVis session cookie in seconds. The default value is set to 24 hours. The value the NagVis session cookie contains will be renewed on every page visit. If a session is idle for more time than configured here it will become invalid. |
| startmodule | overview | The default module to show when none is given by the user |
| startaction | view | The default action to do when none is given by the user |
| startshow | The startshow parameter is only used by some views at the moment. It is used by the Map and the AutoMap modules. |

The backend sections to define the backends are all named [backend_<backend-id>].
In the example the backend_id is live_1.
Depending on the value in backendtype the valid values for the backends have to be set. In this example it is the MKLivestatus backend.
[backend_live_1] backendtype="mklivestatus" htmlcgi="/nagios/cgi-bin" ; the following options depend on the selected backendtype, in this case it is MKLivestatus socket="unix:/usr/local/nagios/var/rw/live"
| Value | Default | Description |
|---|---|---|
| backendtype | mklivestatus | type of backend - MUST be set |
| statushost | The status host can be used to prevent annoying timeouts when a backend is not reachable. This is only useful in multi backend setups. It works as follows: The assumption is that there is a "local" backend which monitors the host of the "remote" backend. When the remote backend host is reported as UP the backend is queried as normal. When the remote backend host is reported as "DOWN" or "UNREACHABLE" NagVis won't try to connect to the backend anymore until the backend host gets available again. The statushost needs to be given in the following format: "<backend_id>:<hostname>" -> e.g. "live_2:nagios" The host needs to be in another backend than the current one to work correctly. |
|
| htmlcgi | /nagios/cgi-bin | Path to the cgi-bin directory of this backend (interesting for multiple backends) |
| custom_1 | First custom variable which is available in the context and hover menus. With this option different custom URLs can be added to the context/hover menus based on the backend used. Might be interesting when adding links to different Nagios instances. | |
| custom_2 | Second custom variable. Same as above. | |
| custom_3 | Third custom variable. Same as above. |
For the backendtype specific options see the backends documentation.
[rotation_demo] maps="demo,demo2" interval=15
| Value | Default | Description |
|---|---|---|
| interval | 15 | Map rotation interval in seconds |
| maps |
Comma separated list of maps to rotate in this pool. You can also add external URLs surrounded by [ and ] (e.g. maps="demo1,[http://localhost/test.php]". The URL has to be reachable and accessible by the server which NagVis is running on. You can add labels in the following format <label>:<map> and <label>:<[url]>. The labels are displayed in the rotation list. It is also possible to add automaps to rotations. Simply prepend the automap name with an @ sign to add an automap to the rotation. |
Options which affect the handling and appearance of the different states in the NagVis installation.
These settings define the state handling behaviour. Mainly it is possible to configure which state will cover another state changing these values. The state with the highest value will become the "summary state" for an object. For example a critical state (5) will cover a warning state (4). Another example: An acknowledged critical state (2) will not cover a warning state (4).
