New Features

Custom Scripts (#3415)

Custom scripts allow for the execution of arbitrary code via the NetBox UI. They can be used to automatically create, manipulate, or clean up objects or perform other tasks within NetBox. Scripts are defined as Python files which contain one or more subclasses of extras.scripts.Script. Variable fields can be defined within scripts, which render as form fields within the web UI to prompt the user for input data. Scripts are executed and information is logged via the web UI. Please see the docs for more detail.

Note: There are currently no API endpoints for this feature. These are planned for the upcoming v2.7 release.

v2.6.0 (2019-06-20)

New Features

Power Panels and Feeds (#54)

NetBox now supports power circuit modeling via two new models: power panels and power feeds. Power feeds are terminated to power panels and are optionally associated with individual racks. Each power feed defines a supply type (AC/DC), amperage, voltage, and phase. A power port can be connected directly to a power feed, but a power feed may have only one power port connected to it.

Additionally, the power port model, which represents a device's power input, has been extended to include fields denoting maximum and allocated draw, in volt-amperes. This allows a device (e.g. a PDU) to calculate its total load compared to its connected power feed.

Caching (#2647)

To improve performance, NetBox now supports caching for most object and list views. Caching is implemented using Redis, which is now a required dependency. (Previously, Redis was required only if webhooks were enabled.)

A new configuration parameter is available to control the cache timeout:

## Cache timeout (in seconds)
CACHE_TIMEOUT = 900

View Permissions (#323)

Django 2.1 introduced the ability to enforce view-only permissions for different object types. NetBox now enforces these by default. You can grant view permission to a user or group by assigning the "can view" permission for the desired object(s).

To exempt certain object types from the enforcement of view permissions, so that any user (including anonymous users) can view them, add them to the new EXEMPT_VIEW_PERMISSIONS setting in configuration.py:

EXEMPT_VIEW_PERMISSIONS = [
    'dcim.site',
    'ipam.prefix',
]

To exclude all objects, effectively disabling view permissions and restoring pre-v2.6 behavior, set:

EXEMPT_VIEW_PERMISSIONS = ['*']

Custom Links (#969)

Custom links are created under the admin UI and will be displayed on each object of the selected type. Link text and URLs can be formed from Jinja2 template code, with the viewed object passed as context data. For example, to link to an external NMS from the device view, you might create a custom link with the following URL:

https://nms.example.com/nodes/?name={{ obj.name }}

Custom links appear as buttons at the top of the object view. Grouped links will render as a dropdown menu beneath a single button.

Prometheus Metrics (#3104)

NetBox now supports exposing native Prometheus metrics from the application. Prometheus is a popular time series metric platform used for monitoring. Metric exposition can be toggled with the METRICS_ENABLED configuration setting; it is not enabled by default. NetBox exposes metrics at the /metrics HTTP endpoint, e.g. https://netbox.local/metrics.

NetBox makes use of the django-prometheus library to export a number of different types of metrics, including:

Per model insert, update, and delete counters
Per view request counters
Per view request latency histograms
Request body size histograms
Response body size histograms
Response code counters
Database connection, execution, and error counters
Cache hit, miss, and invalidation counters
Django middleware latency histograms
Other Django related metadata metrics

For the exhaustive list of exposed metrics, visit the /metrics endpoint on your NetBox instance. See the documentation for more details on using Prometheus metrics in NetBox.

Changes

New Dependency: Redis

Redis is an in-memory data store similar to memcached. While Redis has been an optional component of NetBox since the introduction of webhooks in version 2.4, it is now required to support NetBox's new caching functionality (as well as other planned features). Redis can be installed via your platform's package manager: for example, sudo apt-get install redis-server on Ubuntu or sudo yum install redis on CentOS.

The Redis database is configured using a configuration setting similar to DATABASE in configuration.py:

REDIS = {
    'HOST': 'localhost',
    'PORT': 6379,
    'PASSWORD': '',
    'DATABASE': 0,
    'CACHE_DATABASE': 1,
    'DEFAULT_TIMEOUT': 300,
    'SSL': False,
}

Note that if you were using these settings in a prior release with webhooks, the DATABASE setting remains the same but an additional CACHE_DATABASE setting has been added with a default value of 1 to support the caching backend. The DATABASE setting will be renamed in a future release of NetBox to better relay the meaning of the setting. It is highly recommended to keep the webhook and cache databases seperate. Using the same database number for both may result in webhook processing data being lost during cache flushing events.

Previously, specifying a related object in an API request required knowing the primary key (integer ID) of that object. For example, when creating a new device, its rack would be specified as an integer:

{
    "name": "MyNewDevice",
    "rack": 123,
    ...
}

The NetBox API now also supports referencing related objects by a set of sufficiently unique attrbiutes. For example, a rack can be identified by its name and parent site:

{
    "name": "MyNewDevice",
    "rack": {
        "site": {
            "name": "Equinix DC6"
        },
        "name": "R204"
    },
    ...
}

There is no limit to the depth of nested references. Note that if the provided parameters do not return exactly one object, a validation error is raised.

API Device/VM Config Context Included by Default (#2350)

The rendered config context for devices and VMs is now included by default in all API results (list and detail views). Previously, the rendered config context was available only in the detail view for individual objects. Users with large amounts of context data may observe a performance drop when returning multiple objects. To combat this, in cases where the rendered config context is not needed, the query parameter ?exclude=config_context may be appended to the request URL to exclude the config context data from the API response.

Changes to Tag Permissions

NetBox now makes use of its own Tag model instead of the stock model which ships with django-taggit. This new model lives in the extras app and thus any permissions that you may have configured using "Taggit | Tag" should be changed to now use "Extras | Tag." Also note that the admin interface for tags has been removed as it was redundant to the functionality provided by the front end UI.

CORS_ORIGIN_WHITELIST Requires URI Scheme

If you have the CORS_ORIGIN_WHITELIST configuration parameter defined, note that each origin must now incldue a URI scheme. This change was introuced in django-cors-headers 3.0.
