Hi, Previous to Luminous you could run 'ceph -w' and get a continues output of how the cluster is performing. You would get IOps and such. To get this done with Luminous you need to do something like: $ watch ceph -s Although this works it is less efficient then -w used to be: 1. Spawn Python interpreter 2. Create connection with the MON(s) 3. Fetch OSDMap 4. Fetch statistics And do this all every 2 seconds (or which interval you set). So I was thinking about this: $ ceph -s <interval> If you provide a interval the process will not exit but it will refresh the screen every X seconds while keeping the Python interpreter live and also keep the MON connection imitated. It's actually just running the mon command 'status' every X seconds and refreshing the screen. Although we have the 'iostat' Mgr module in Mimic it doesn't do exactly the same as status does. I think it's the status Mgr Module which is responsible for this, isn't it?
