We do have the audit log, which records all the commands that the monitor processes. It's a special "channel" within the main cluster log, that's written out to a separate ceph.audit.log file by default. You can get at the most recent messages with "ceph log last audit" Both the audit log and the cluster log are stored in a limited sized buffer inside the mon, and also written out to files -- for the longer term record keeping it's up to the admin's log rotation etc to keep the record. The audit log can get quite spammy if you have e.g. external monitoring tools that hit the command interface. John > Haven't given it much thought yet as to where to store the history.
