Per OSD usage metrics are now available in the OSDs dashboard. The
dashboard now includes a new section that displays a histogram of of the
utilization of each OSD in the cluster. This can be useful for identifying
OSDs that are outliers in terms of utilization, and may need to be
rebalanced. Additionally, there is a histogram displaying the usage of the
bluestoreDB for each OSD.
