How interpret dashboard meters in UI?


How should the meters on a cluster dashboard be interpreted? Looks like (clockwise) the first line shows the node with the lowest allocation of that resource, the dot is sum allocation of the resource for all nodes, and the second line is the node with the highest allocation, and I’m assuming this ‘reserved’ resource aligns with ‘resources.requests’ in, say, a deploy or pod definition. Anything I’m missing?

As an aside, it would be cool to add another layer in those meters to see actual usage so one could see at a quick glance reserved vs actual!
