Hi Rhian,
not sure if you fond an answer already.
I believe in luminous and mimic it is only possible to extract compression
information on osd device level. According to the recent announcement of
nautilus, this seems to get better in the future.
If you want to check if anything is compressed, you need to find a data-OSD
that's in a data pool of your cepf fs. On this OSD you can extract low-level
information, including compression statistics. You find details in this
conversation:

Hope that helps,

Subject: [ceph-users] Checking cephfs compression is working
How do you confirm that cephfs files and rados objects are being compressed?
I don't see how in the docs.
