I suppose you would like to know how much data are using your VMs using
thin logical volumes.
For this you can simply use lvs.
Commented output on my system:
lvs | grep -i data
LV VG Attr LSize Pool Origin Data%
data pve twi-aotz-- 100.00g 0.65
vm-404-disk-1 pve Vwi-a-tz-- 32.00g data 2.02
Here I have a 'data' thinpool LV, like you, containing a single disk
image LV 'vm-404-disk-1'
On this disk image 2.02% of the 32GB have been already allocated. which
represents 0.65% of the total available size on the thin pool.
