Hello, Andy here from Netdata.
I think pointing Netdata Prometheus collector at the metrics endpoint should for sure be an easy way to pull the metrics from the metrics endpoint into Netdata

I need to learn a bit more about LXD VM’s and how may or may not be different than normal VM’s but just wanted to mention the /metrics approach as one potential quick solution.
