Look at the metrics relabel config between this line: https://github.com/scylladb/scylla-monitoring/blob/1ab337a505e4f57ec15001480d0898c6d18c8a76/prometheus/prometheus.yml.template#L75 And this line: https://github.com/scylladb/scylla-monitoring/blob/1ab337a505e4f57ec15001480d0898c6d18c8a76/prometheus/prometheus.yml.template#L126

@amnonh - do we need to update the monitoring in the operator? 4.6 is out, it's a good time to do it?

I'm removing myself as assigned, assign me if you need more information or if you want to me to do anything

@amnonh @mykaul's directions were that monitoring team should be updating the dashboard definitions here, that's the reason this was assigned to you.

I've opened the issue around the Prometheus relabel config, which is broken for 2023.1 and higher.
