netbox-notices 0.2.4

Track maintenance and outage events across various NetBox models from vendors and internal sources.

NetBox Notices

Repository: github.com/jsenecal/netbox-notices
Documentation: jsenecal.github.io/netbox-notices
PyPI: pypi.org/project/netbox-notices

Original Project: Forked and inspired from jasonyates/netbox-circuitmaintenance, differs in the ability to track more than just maintenances, and circuits.

A NetBox plugin built to track maintenance and outage events across various NetBox models. This plugin is agnostic in that it is only built to store data surrounding maintenance/outage events and provide an overview of historical, active and upcoming events. The plugin tracks events at the provider level and associates impact across multiple NetBox object types (circuits, devices, virtual machines, power feeds, sites, etc.).

The plugin does not directly provide an automated approach to ingesting provider notifications, instead it extends NetBox's extensive REST API and provides GET/POST/PUT/PATCH methods to manage events. The plugin is intended to be coupled with an automated parser to handle the parsing of provider notifications and the delivery of the events to the plugin's REST API. Several example parsers are documented here.

Important Note: This is a significant refactoring from the original netbox-circuitmaintenance plugin. There is no upgrade path from the original plugin. If you are using the original plugin, you will need to migrate your data manually.

Compatibility

This plugin requires NetBox 4.4.1 or higher.

NetBox Version	Plugin Version
4.4.1+	0.2.x

Installing

A working installation of Netbox 4.4.1+ is required - see official documentation.

Package Installation

Activate your virtual env and install via pip:

$ source /opt/netbox/venv/bin/activate
(venv) $ pip install netbox-notices

To ensure the plugin is automatically re-installed during future upgrades, add the package to your local_requirements.txt:

# echo netbox-notices >> local_requirements.txt

Enable the Plugin

In the Netbox configuration.py configuration file add or update the PLUGINS parameter, adding vendor_notification:

PLUGINS = [
    'notices'
]

PLUGINS_CONFIG = {
    "notices": {},
}

Configuration

The plugin supports configuration of which NetBox object types can be linked to maintenance and outage events. By default, the plugin allows linking to circuits, power feeds, and sites.

Default Configuration

If you don't specify any configuration, the plugin uses these defaults:

PLUGINS_CONFIG = {
    "notices": {
        "allowed_content_types": [
            "circuits.Circuit",
            "dcim.PowerFeed",
            "dcim.Site",
        ]
    }
}

Custom Configuration

You can customize which object types are allowed by specifying the allowed_content_types setting. Content types are specified in the format app_label.model_name.

Example: Add Devices and Virtual Machines

PLUGINS_CONFIG = {
    "notices": {
        "allowed_content_types": [
            "circuits.Circuit",
            "dcim.Device",
            "dcim.PowerFeed",
            "dcim.Site",
            "virtualization.VirtualMachine",
        ]
    }
}

Example: Minimal Configuration (Circuits Only)

PLUGINS_CONFIG = {
    "notices": {
        "allowed_content_types": [
            "circuits.Circuit",
        ]
    }
}

Example: Extended Configuration

PLUGINS_CONFIG = {
    "notices": {
        "allowed_content_types": [
            "circuits.Circuit",
            "dcim.Device",
            "dcim.Interface",
            "dcim.PowerFeed",
            "dcim.Rack",
            "dcim.Site",
            "ipam.IPAddress",
            "ipam.Prefix",
            "virtualization.VirtualMachine",
            "virtualization.VMInterface",
        ]
    }
}

How Configuration Affects Behavior

• Only object types listed in allowed_content_types will appear in the Impact creation forms
• The API will reject attempts to create impacts for non-allowed object types
• Changing the configuration requires a NetBox restart
• This setting controls which objects can be linked via the Impact model to maintenance and outage events

Common NetBox Object Types

Content Type	Description
circuits.Circuit	Network circuits
circuits.Provider	Service providers
dcim.Device	Physical network devices
dcim.Interface	Device network interfaces
dcim.PowerFeed	Power supply connections
dcim.PowerPanel	Power distribution panels
dcim.Rack	Equipment racks
dcim.Site	Physical locations
ipam.IPAddress	IP addresses
ipam.Prefix	IP prefixes/subnets
virtualization.VirtualMachine	Virtual machines
virtualization.VMInterface	VM network interfaces

Apply Database Migrations

Apply database migrations with Netbox manage.py:

(venv) $ python manage.py migrate

Restart Netbox

Restart the Netbox service to apply changes:

sudo systemctl restart netbox

Outage Tracking

In addition to planned maintenance, this plugin supports tracking unplanned outage events:

Key Features

• Optional End Time: Outages can be created without an end time, which becomes required when marking as resolved
• ETR Tracking: Track Estimated Time to Repair with full revision history via NetBox's changelog
• Outage Status Workflow:
  • REPORTED: Initial state when outage is reported
  • INVESTIGATING: Team is investigating root cause
  • IDENTIFIED: Root cause identified, working on fix
  • MONITORING: Fix applied, monitoring for stability
  • RESOLVED: Outage fully resolved (requires end time)
• Shared Impact Model: Uses the same impact tracking as maintenance events (Impact model)
• Unified View: View both maintenance and outages together in a single interface
• Flexible Object Support: Link outages to any configured NetBox object type

Calendar & iCal Integration

The plugin provides an interactive calendar view and iCal feed for integrating maintenance events with external calendar applications.

Data Models

The plugin uses four main models to track maintenance and outage events:

Maintenance

Represents a planned maintenance event from a provider. Key fields:

• name: Event identifier
• summary: Description of the maintenance
• provider: Foreign key to NetBox Provider
• start, end: Maintenance window times
• status: TENTATIVE, CONFIRMED, CANCELLED, IN-PROCESS, COMPLETED, RE-SCHEDULED, UNKNOWN
• internal_ticket: Your organization's tracking ticket reference
• acknowledged: Whether the event has been acknowledged

Outage

Represents an unplanned outage event from a provider. Key fields:

• name: Event identifier
• summary: Description of the outage
• provider: Foreign key to NetBox Provider
• start, end: Outage window times (end is optional until resolved)
• status: REPORTED, INVESTIGATING, IDENTIFIED, MONITORING, RESOLVED
• estimated_time_to_repair: ETR timestamp (tracked with changelog history)
• internal_ticket: Your organization's tracking ticket reference
• acknowledged: Whether the event has been acknowledged

Impact

Links maintenance or outage events to affected NetBox objects using Django's Generic Foreign Key pattern:

• maintenance or outage: Foreign key to the event (mutually exclusive)
• content_type: The type of affected object (e.g., "circuits.circuit", "dcim.device")
• object_id: The ID of the affected object
• impact: Impact level - NO-IMPACT, REDUCED-REDUNDANCY, DEGRADED, OUTAGE

The Impact model allows linking events to any NetBox object type configured in allowed_content_types.

EventNotification

Stores raw email notifications received from providers:

• maintenance or outage: Foreign key to the associated event
• email: Binary email data
• email_body: Extracted body text
• subject: Email subject line
• email_from: Sender address
• email_received: Receipt timestamp
