Report on diff between rendered & actual device configuration

NetBox v3.5 introduced native configuration template rendering for devices. This plugin would be an extension of that functionality, automatically comparing the rendered configuration for a device to its actual configuration, retrieved from the device itself. When the two differ, a report showing the differences is created and stored for analysis.

Specific functionality to be included in this plugin is listed below:

• Ability to designate which devices should be included via a tag or custom field

• Integration w/NAPALM to facilitate the retrieval of live device configs (this may depend on the existing NAPALM plugin)

• A means of running a recurring background task to check the config of each device

• A view listing all config analyses and the status of each

• An option to exclude lines matching a regex from diff reporting (e.g. NTP clock offsets)

• A REST API endpoint to initiate and report on checks for individual devices
