Inserting object data into local config context?

[llamafilm]

I saw this interesting presentation from an engineer at Nokia, describing how they use Netbox config contexts to generate Telegraf configs. Unfortunately I could not understand much of the audio.

I'm trying to figure out how this would work. If I want to monitor device health using Telegraf SNMP input plugin, the config needs to know the IP address of each device. So I could put most of the SNMP config in the Device Model config context, and then I would need a way to insert the device's Primary IP address using local config context. Is this possible?

I did a little testing and found that get_config_context() is fairly slow when iterating though a large number of devices. Instead, I think it will be more efficient to store text files on disk for each Telegraf template, and use Netbox script to replace strings and build the full config that way.

I haven't watched the video, but for the device's IP address I'd suggest you use its primary_ip address attribute.

(If you are configuring a device from Netbox data, the information you need doesn't all have to come from config_context data. This is mainly intended for those settings which are often shared between all devices in a site, rack, tenant etc. Things which are set individually on a device could be standard Netbox attributes or custom fields)
