Have you tried asking in the discord? I think it should work if you use the correct metrics flags (see readme of this repo for help), and nimbus might have to be built with the "insecure" flag set to true (I think it was NIMFLAGS="-d:insecure") to enable extra HTTP functionality like metrics (this might have changed, ask Nimbus team).

[joebiker]

@protolambda Yes, I've done that. I compiled using the NIMFLAGS suggested.
I would revert back to nimbus 0.6.5 to show the difference in stats, but I'm struggling to get eth2stats to run as a daemon on mac launchctl (exits 1 everytime).

[joebiker]

I see this in the README.md
The process_resident_memory_bytes gauge is extracted from the Prometheus metrics endpoint.

However I'm not sure how it applies. I am running Prometheus, however there's no configuration for including Prometheus into command line options?

[protolambda]

That's poor wording in the readme, it should just grab it from the metrics endpoint of the eth2 client. Prometheus is the more common consumer of the metrics endpoint, but not relevant here.

Are you using all the nimbus metrics flags? --metrics --metrics-port=8080 --metrics-address=0.0.0.0
You could try curl the /metrics endpoint to check if it can be reached and has the expected contents.

[joebiker]

Yes, I checked the /metrics endpoint on Nimbus 0.6.6, I've listed the contents of what I consider 'close' to the memory usage statistic.
