# System Parameters ## BASE_PATH Default: None The base URL path to use when accessing NetBox. Do not include the scheme or domain name. For example, if installed at https://example.com/netbox/, set: ```python BASE_PATH = 'netbox/' ``` --- ## DEFAULT_LANGUAGE Default: `en-us` (US English) Defines the default preferred language/locale for requests that do not specify one. (This parameter maps to Django's [`LANGUAGE_CODE`](https://docs.djangoproject.com/en/stable/ref/settings/#language-code) internal setting.) --- ## DOCS_ROOT Default: `$INSTALL_ROOT/docs/` The filesystem path to NetBox's documentation. This is used when presenting context-sensitive documentation in the web UI. By default, this will be the `docs/` directory within the root NetBox installation path. (Set this to `None` to disable the embedded documentation.) --- ## EMAIL In order to send email, NetBox needs an email server configured. The following items can be defined within the `EMAIL` configuration parameter: * `SERVER` - Hostname or IP address of the email server (use `localhost` if running locally) * `PORT` - TCP port to use for the connection (default: `25`) * `USERNAME` - Username with which to authenticate * `PASSWORD` - Password with which to authenticate * `USE_SSL` - Use SSL when connecting to the server (default: `False`) * `USE_TLS` - Use TLS when connecting to the server (default: `False`) * `SSL_CERTFILE` - Path to the PEM-formatted SSL certificate file (optional) * `SSL_KEYFILE` - Path to the PEM-formatted SSL private key file (optional) * `TIMEOUT` - Amount of time to wait for a connection, in seconds (default: `10`) * `FROM_EMAIL` - Sender address for emails sent by NetBox !!! note The `USE_SSL` and `USE_TLS` parameters are mutually exclusive. Email is sent from NetBox only for critical events or if configured for [logging](#logging). If you would like to test the email server configuration, Django provides a convenient [send_mail()](https://docs.djangoproject.com/en/stable/topics/email/#send-mail) function accessible within the NetBox shell: ```no-highlight # python ./manage.py nbshell >>> from django.core.mail import send_mail >>> send_mail( 'Test Email Subject', 'Test Email Body', 'noreply-netbox@example.com', ['users@example.com'], fail_silently=False ) ``` --- ## HTTP_PROXIES Default: Empty A dictionary of HTTP proxies to use for outbound requests originating from NetBox (e.g. when sending webhook requests). Proxies should be specified by schema (HTTP and HTTPS) as per the [Python requests library documentation](https://requests.readthedocs.io/en/latest/user/advanced/#proxies). For example: ```python HTTP_PROXIES = { 'http': 'http://10.10.1.10:3128', 'https': 'http://10.10.1.10:1080', } ``` If more flexibility is needed in determining which proxy to use for a given request, consider implementing one or more custom proxy routers via the [`PROXY_ROUTERS`](#proxy_routers) parameter. --- ## INTERNAL_IPS Default: `('127.0.0.1', '::1')` A list of IP addresses recognized as internal to the system, used to control the display of debugging output. For example, the debugging toolbar will be viewable only when a client is accessing NetBox from one of the listed IP addresses (and [`DEBUG`](./development.md#debug) is true). --- ## ISOLATED_DEPLOYMENT Default: False Set this configuration parameter to True for NetBox deployments which do not have Internet access. This will disable miscellaneous functionality which depends on access to the Internet. !!! note If Internet access is available via a proxy, set [`HTTP_PROXIES`](#http_proxies) instead. --- ## JINJA2_FILTERS Default: `{}` A dictionary of custom jinja2 filters with the key being the filter name and the value being a callable. For more information see the [Jinja2 documentation](https://jinja.palletsprojects.com/en/3.1.x/api/#custom-filters). For example: ```python def uppercase(x): return str(x).upper() JINJA2_FILTERS = { 'uppercase': uppercase, } ``` --- ## LOGGING By default, all messages of INFO severity or higher will be logged to the console. Additionally, if [`DEBUG`](./development.md#debug) is False and email access has been configured, ERROR and CRITICAL messages will be emailed to the users defined in [`ADMINS`](./miscellaneous.md#admins). The Django framework on which NetBox runs allows for the customization of logging format and destination. Please consult the [Django logging documentation](https://docs.djangoproject.com/en/stable/topics/logging/) for more information on configuring this setting. Below is an example which will write all INFO and higher messages to a local file: ```python LOGGING = { 'version': 1, 'disable_existing_loggers': False, 'handlers': { 'file': { 'level': 'INFO', 'class': 'logging.FileHandler', 'filename': '/var/log/netbox.log', }, }, 'loggers': { 'django': { 'handlers': ['file'], 'level': 'INFO', }, }, } ``` ### Available Loggers * `netbox..` - Generic form for model-specific log messages * `netbox.auth.*` - Authentication events * `netbox.api.views.*` - Views which handle business logic for the REST API * `netbox.reports.*` - Report execution (`module.name`) * `netbox.scripts.*` - Custom script execution (`module.name`) * `netbox.views.*` - Views which handle business logic for the web UI --- ## MEDIA_ROOT Default: `$INSTALL_ROOT/netbox/media/` The file path to the location where media files (such as image attachments) are stored. By default, this is the `netbox/media/` directory within the base NetBox installation path. --- ## PROXY_ROUTERS Default: `["utilities.proxy.DefaultProxyRouter"]` A list of Python classes responsible for determining which proxy server(s) to use for outbound HTTP requests. Each item in the list can be the class itself or the dotted path to the class. The `route()` method on each class must return a dictionary of candidate proxies arranged by protocol (e.g. `http` and/or `https`), or None if no viable proxy can be determined. The default class, `DefaultProxyRouter`, simply returns the content of [`HTTP_PROXIES`](#http_proxies). --- ## REPORTS_ROOT Default: `$INSTALL_ROOT/netbox/reports/` The file path to the location where [custom reports](../customization/reports.md) will be kept. By default, this is the `netbox/reports/` directory within the base NetBox installation path. --- ## SCRIPTS_ROOT Default: `$INSTALL_ROOT/netbox/scripts/` The file path to the location where [custom scripts](../customization/custom-scripts.md) will be kept. By default, this is the `netbox/scripts/` directory within the base NetBox installation path. --- ## SEARCH_BACKEND Default: `'netbox.search.backends.CachedValueSearchBackend'` The dotted path to the desired search backend class. `CachedValueSearchBackend` is currently the only search backend provided in NetBox, however this setting can be used to enable a custom backend. --- ## STORAGE_BACKEND Default: None (local storage) The backend storage engine for handling uploaded files (e.g. image attachments). NetBox supports integration with the [`django-storages`](https://django-storages.readthedocs.io/en/stable/) and [`django-storage-swift`](https://github.com/dennisv/django-storage-swift) packages, which provide backends for several popular file storage services. If not configured, local filesystem storage will be used. The configuration parameters for the specified storage backend are defined under the `STORAGE_CONFIG` setting. --- ## STORAGE_CONFIG Default: Empty A dictionary of configuration parameters for the storage backend configured as `STORAGE_BACKEND`. The specific parameters to be used here are specific to each backend; see the documentation for your selected backend ([`django-storages`](https://django-storages.readthedocs.io/en/stable/) or [`django-storage-swift`](https://github.com/dennisv/django-storage-swift)) for more detail. If `STORAGE_BACKEND` is not defined, this setting will be ignored. --- ## TIME_ZONE Default: UTC The time zone NetBox will use when dealing with dates and times. It is recommended to use UTC time unless you have a specific need to use a local time zone. Please see the [list of available time zones](https://en.wikipedia.org/wiki/List_of_tz_database_time_zones). --- ## TRANSLATION_ENABLED Default: True Enables language translation for the user interface. (This parameter maps to Django's [USE_I18N](https://docs.djangoproject.com/en/stable/ref/settings/#std-setting-USE_I18N) setting.)
