Hi, all
As my understand, command "ceph daemon osd.x perf dump objecters" should
output the perf data of osdc(librados). But when i use this command,
why all those values are zero expcept map_epoch and map_inc. Follow is
the result(It has fio test with rbd ioengine on the cluster):
$ sudo ceph daemon osd.10 perf dump objecter
