By slicing and dicing Ceph log files and emitting CSV files ready for importing into a spreadsheet, these scripts help collate thousands of messages across hours or days so that we can discern patterns. They are especially useful for narrowing in on nodes or OSDs that are loci of chronic slow / blocked requests.

Common tasks

In this section we cover procedures for a number of common tasks that Ceph admins execute as needed. These include managing flags and services, dealing with component failures, cluster expansion, and balancing OSD utilization. We'll also touch on upgrades between Ceph releases.
