Description Mike Hackett 2021-08-31 15:39:44 UTC 
Description of problem:

Increasing RAM per OSD in a Ceph cluster can improve the performance of the OSD in some use cases. By default we deploy 5GB per OSD, which in some cases can limit the performance of the OSD when the physical node has additional RAM available that "could" be allocated to the OSD's. 

The dashboard can provide the details pulled from Bluestore stats in order to display the onode hit/miss counters to help inform the customer if increasing RAM per OSD could help improve the performance for their cluster. With this data the customer can make the decision if they want to increase the avail memory per OSD or increase the RAM in the system.
