This reads wrong, why do we need an avg for a metric reported as an avg.

The raw thought is to make the overall graph more straightforward. As there are a lot of DN DB instances in a normal cluster, we could detect the overall trend instead of each DB. Besides that here I put two metrics together with two Y-axises.
Otherwise, it would be hard to distinguish the overall trend with too many instances.
(Even users could add more variables to control the number of exhibiting instances)
