Unfortunately the *ceph -w* command is a tool that a system administrator uses for real time information, means there is no history or looking backward what happened at a given time. The ceph-log program stores the output of *ceph -w* into a logfile and rotate its. This allows the system administrator to go back and check what exactly happened in detail within a Ceph storage cluster at any given time. ## OPTIONS The ceph-log program has no options. ## FILES The following files are used: **/etc/open-infrastructure/ceph-tools.conf** Configuration file. **/var/log/open-infrastructure/ceph-watch.log** Ceph cluster logfile. ## SEE ALSO [storage-tools(7)](/storage-tools/7.md). ## HOMEPAGE More information about storage-tools and the Open Infrastructure project can be found on the homepage at https://open-infrastructure.net. ## CONTACT Bug reports, feature requests, help, patches, support and everything else are welcome on the Open Infrastructure Software Mailing List \.
