[ceph-users] Discovery (port 8765) service not starting

Hi, I'm running reef, with locally-built containers based on upstream .debs. I've now enabled prometheus metrics thus: ceph mgr module enable prometheus And that seems to have worked (the active mgr is listening on port 9283); but per the docs[0] there should also be a service discovery endpoint (on port 8765) that I can point Prometheus' http_sd_config at. But there is in fact no listener on that port, nor anything obvious in logs if I failover the mgr - see a log extract here: https://phabricator.wikimedia.org/P68521 Is there something else I need to be doing to get the service discovery endpoint working? Thanks, Matthew [0] https://docs.ceph.com/en/reef/cephadm/services/monitoring/#deploying-monitor...
