Hi Manuel,
this behavior was primarily updated in Nautilus by
https://github.com/ceph/ceph/pull/19454
Per-pool stats under "POOLS" section are now the most precise means to
answer various questions about space utilization.
'STORED" column provides net amount of data for a specific pool.
You can use "ceph df detail --format json|json-pretty" to obtain a
report in json format for further processing../.
Hope this helps,
Igor
