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
{
"objecter": {

}
Anyone could tell why?
Thanks!

Objecter is the client side, but you're dumping stats on the osd. The
only time it is used as a client there is with cache tiering.

Sure, thanks!
But i think client like qemu use librbd will also run into this perf statistics, any way
we could dump the perf statistics for other client side like qemu.
Sorry if there exist some document on internet and i didn't got it by searching.
Thanks!
