Description
In Filesystems page, currently we use mds.inodes counter for Dentries, which is not aligned to output of ceph fs status command (which use mds_mem.dn).
e.g.
versus

For dns (Dentries), CLI command switched from using mds.inodes to mds_mem.dn in this change , which suggests that mds_mem.dn is more clear and accurate than mds.inodes.
Also in MDS's counter chart on detail tab, currently counter mds.inodes are displayed. Which also inconsistent with inodes column in Ranks table (display mds_mem.ino counter).
