Hi Jan, first of all thanks for this dashboard. A few comments: -) 'vonage-status-panel' is needed, which isn't mentioned in the ReadMe -) Using ceph 12.2.4 the mon metric for me is apparently called 'ceph_mon_quorum_count' not 'ceph_mon_quorum_status' And a question: Is there a way to get

Hi, looking at the outputs below the following puzzles me: You have two nodes but repl.size 3 for your test-data pool. With the default crushmap this won't work as it tries to replicate on different nodes. So either change to rep.size 2, or add another node ;-) best regards, Kurt Jogi

Re: [ceph-users] cluster_network ignored

To see where your OSDs and Mon are listening, you have various cmds in Linux, e.g: 'lsof -ni | grep ceph' - you should see one LISTEN line for the monitor, 2 LISTEN lines for the OSDs and a lot of ESTABLISHED lines, which indicate communication between OSDs and OSDs and clients 'netstat -atn |

Re: [ceph-users] ReAsk: how to tell ceph-mon to listen on a specific address only

Hi, that's by design. The monitor always listens to the public side only, if a public network is defined. If you want everything in the cluster network, just don't specify a seperate public/cluster network. But that's all documented in great detail at
