[ceph-users] osd_memory_target values

Hi all, for a ceph cluster with RAM size of 256 GB per node, I would increase the osd_memory_target from default 4GB up to 12GB. Through the ceph dashboard, different values are given to set the new value (global, mon, ..., osd). Is there any difference between them? From my point of view, I should simply set the osd value to 12 GB, am I right? Best, Mevludin
