I would like to stay away from using the workaround.

First I did a redeployment of prometheus and later ceph-exporter, but still no 
data. After the deployment of ceph-exporter I saw the following messages (2 
times, for each host running prometheus): Reconfiguring daemon 
prometheus.<host>.
You mention missing a configuration, but I can't find any specific 
configuration options in the docs; 
https://docs.ceph.com/en/reef/mgr/prometheus/ and 
https://docs.ceph.com/en/reef/cephadm/services/monitoring/

Kind regards,
Sake
