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,

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.
