This dashboard will let you compare metrics from Kubernetes nodes side-by-side from different clusters. It was used to compare different Kubernetes distributions which you can read about on this blog post.

You need to create clusters and install the node-exporter (yaml below ) and set up prometheus to scrape each node. Then add a prometheus datasource in grafana and import this dashboard.
