clog is the 'cluster log', that gets aggregated into a single log stream and replicated on each monitor (normally /var/log/ceph/ceph.log). It's for high-level events of interest to the entire cluster. The intended consumer is the system administrator. dout is for debugging a single process. It's used by a developer (or a savvy admin). sage _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
