Prometheus Monitoring for LXD?

Has anyone set up Prometheus Monitoring for LXD? If so, what exporter do you recommend?

LXD provides metrics for all running instances. You can learn more about it here: Instance metrics - LXD documentation

Thank you for the link. Is there any way to have it run without a certificate though, so I can manually check the available metrics at ip:8443/metrics?

If you just want to look at them, you can do lxc query /1.0/metrics, for accessing from prometheus, you’ll want to generate a TLS certificate, add that to the LXD trust store with --type=metrics and then pass it on to prometheus to scrape LXD.
