And yes - first 3 parameters from this list are the right and the only
way to inspect compression effectiveness so far.
Corresponding updates to show that with "ceph df" are on the way and are
targeted for Nautilus.
Thanks,
Igor

I filled up an RBD in a compressed pool (aggressive) in my test
cluster with 1TB of zeros. The bluestore OSDs in the cluster all show
similar to this. Am I missing something here? Is there any other
method to determining compression ratios?

Finally, I've founded the command:
ceph daemon osd.1 perf dump | grep bluestore
And there you have compressed data

Hi,
Is there any command or tool to show effectiveness of bluestore
compression?
I see the difference (in ceph osd df tree), while uploading a
object to ceph, but maybe there are more friendly method to do it.
