Hi
We just recently integrated netbox and use it as service discovery for Prometheus (we use https://github.com/FlxPeters/netbox-prometheus-sd for this task). Are you trying to scrape netbox to get metrics (according to https://netbox.readthedocs.io/en/stable/additional-features/prometheus-metrics/) or are you trying to use netbox as a service discovery mechanism?
