.OSD ids in 'Filestore OSD latencies' are no longer repeated
Previously, after rebooting OSDs, on the Red Hat Storage Dashboard page _Ceph OSD Information_ the OSD IDs were repeated in the section _Filestore OSD Latencies_.
With this update to {product} the OSD IDs are no longer repeated on reboot of an OSD node in the _Ceph OSD Information_ dashboard. This was fixed as a part of a redesign of the underlying data reporting.
