Re: commit_latency equals apply_latency on bluestore

As I mentioned in that email, the apply and commit values in BlueStore are equivalent. They're exported because it's part of the interface (thanks to FileStore), but they won't differ. If you're doing monitoring or graphs, just pick one.

Hi Cephers, Hi Gregory,

I consider same case like here, commit_latency==apply_latency in ceph osd perf


What's the meaning of commit_latency and apply_latency in bluestore OSD setups[? How useful is it when troubleshooting? How does it correspond to separated block.db and block.wal ?

Thanks
Jakub
