Subject: osd: add % used to each OSD
X-Git-Tag: v1.0~38^2
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=f6876810d319c0a8aa483147c53c8362082d3dcd;p=cephmetrics.git

osd: add % used to each OSD

percent used was not available within the osd metric tree only the
physical disk. With the inclusion under the osd, the percent_used can
reference the osd_id directly easier in any queries
