Miscellaneous Parameters

ADMINS

NetBox will email details about critical errors to the administrators listed here. This should be a list of (name, email) tuples. For example:

ADMINS = [
    ['Hank Hill', 'hhill@example.com'],
    ['Dale Gribble', 'dgribble@example.com'],
]

Dynamic Configuration Parameter

Sets content for the bottom banner in the user interface.

Dynamic Configuration Parameter

This defines custom content to be displayed on the login page above the login form. HTML is allowed.

Dynamic Configuration Parameter

Sets content for the top banner in the user interface.

Tip

If you'd like the top and bottom banners to match, set the following:

BANNER_TOP = 'Your banner text'
BANNER_BOTTOM = BANNER_TOP

CHANGELOG_RETENTION

Dynamic Configuration Parameter

Default: 90

The number of days to retain logged changes (object creations, updates, and deletions). Set this to 0 to retain changes in the database indefinitely.

Warning

If enabling indefinite changelog retention, it is recommended to periodically delete old entries. Otherwise, the database may eventually exceed capacity.

ENFORCE_GLOBAL_UNIQUE

Dynamic Configuration Parameter

Default: False

By default, NetBox will permit users to create duplicate prefixes and IP addresses in the global table (that is, those which are not assigned to any VRF). This behavior can be disabled by setting ENFORCE_GLOBAL_UNIQUE to True.

FILE_UPLOAD_MAX_MEMORY_SIZE

Default: 2621440 (2.5 MB).

The maximum amount (in bytes) of uploaded data that will be held in memory before being written to the filesystem. Changing this setting can be useful for example to be able to upload files bigger than 2.5MB to custom scripts for processing.

GRAPHQL_ENABLED

Dynamic Configuration Parameter

Default: True

Setting this to False will disable the GraphQL API.

JOBRESULT_RETENTION

Dynamic Configuration Parameter

Default: 90

The number of days to retain job results (scripts and reports). Set this to 0 to retain job results in the database indefinitely.

Warning

If enabling indefinite job results retention, it is recommended to periodically delete old entries. Otherwise, the database may eventually exceed capacity.

MAINTENANCE_MODE

Dynamic Configuration Parameter

Default: False

Setting this to True will display a "maintenance mode" banner at the top of every page. Additionally, NetBox will no longer update a user's "last active" time upon login. This is to allow new logins when the database is in a read-only state. Recording of login times will resume when maintenance mode is disabled.

MAPS_URL

Dynamic Configuration Parameter

Default: https://maps.google.com/?q= (Google Maps)

This specifies the URL to use when presenting a map of a physical location by street address or GPS coordinates. The URL must accept either a free-form street address or a comma-separated pair of numeric coordinates appended to it.

MAX_PAGE_SIZE

Dynamic Configuration Parameter

Default: 1000

A web user or API consumer can request an arbitrary number of objects by appending the "limit" parameter to the URL (e.g. ?limit=1000). This parameter defines the maximum acceptable limit. Setting this to 0 or None will allow a client to retrieve all matching objects at once with no limit by specifying ?limit=0.

METRICS_ENABLED

Default: False

Toggle the availability Prometheus-compatible metrics at /metrics. See the Prometheus Metrics documentation for more details.

PREFER_IPV4

Dynamic Configuration Parameter

Default: False

When determining the primary IP address for a device, IPv6 is preferred over IPv4 by default. Set this to True to prefer IPv4 instead.

QUEUE_MAPPINGS

Allows changing which queues are used internally for background tasks.

QUEUE_MAPPINGS = {
    'webhook': 'low',
    'report': 'high',
    'script': 'high',
}

If no queue is defined the queue named default will be used.

RELEASE_CHECK_URL

Default: None (disabled)

This parameter defines the URL of the repository that will be checked for new NetBox releases. When a new release is detected, a message will be displayed to administrative users on the home page. This can be set to the official repository ('https://api.github.com/repos/netbox-community/netbox/releases') or a custom fork. Set this to None to disable automatic update checks.

Note

The URL provided must be compatible with the GitHub REST API.

RQ_DEFAULT_TIMEOUT

Default: 300

The maximum execution time of a background task (such as running a custom script), in seconds.
