Shouldn't this be rather implemented in 2.0? switching to that version.

*** Bug 1295810 has been marked as a duplicate of this bug. ***

Yes this should be implemented in 2.0 so that USM can consume

We don't have this in the data from ceph which looks like this:

Either rhs-controller can schedule a utilization check with salt or Ceph needs to grown the capability first.

Which one would be a better choice in your opinion?

Can calamari use 'ceph osd df' command to get utilization from ceph and expose it through an API?. We expect per OSD based utilization data here

That is a possibility. It should take 2 days

line 7: Require API to retrieve the osd utilization
