Diamond is deprecated in favour of prometheus. I checked existing dashboards and there's a number of using metrics which should also be provided by prometheus-node-exporter:
[] https://grafana.wikimedia.org/dashboard/db/cloudvps-eqiad1
(network and load stats, those should all be covered by prometheus-node-exporter)
[] https://grafana.wikimedia.org/dashboard/db/cloud-capacity-planning
(CPU, memory, load, disk stats)
[] https://grafana.wikimedia.org/dashboard/db/labstore1004-1005
(load, IO, network stats)
These seem obsolete and can probably be removed entirely:
