Hi, I keep reading recommendations about disabling debug logging in Ceph in order to improve performance. There are two things that are unclear to me though: a. what do we lose if we decrease default debug logging and where is the sweet point in order to not lose critical messages? I would say for example that we would lose OSD traces after a random OSD crash if we set debug level of osd subsystem to zero (log and memory). Or a "Errno 24: Too many open files" on mon logs if we set debug level of mon subsystem to zero. b. is there a recommended set of debug settings to mute in client nodes versus the Ceph daemons nodes? I mean are there settings that you would mute in client nodes, but prefer to keep them on default levels on Ceph nodes? Best regards, Kostis
