Since it's inception Ceph has lacked an overall health-check tool which would easily highlight an issue inside the Ceph cluster. The ceph status
and ceph health detail
commands exist and are good for providing overall cluster health details but do not point the user in any concrete direction if there is a more complex issue. The creation of the ceph-medic
project enables running a single command to poll multiple predefined checks on a Ceph cluster. These checks range from best practice recommendations to validation of keyrings and directory ownership. The ceph-medic
project continues to develop at a fast pace and new checks are added often.

Overview of this book
This Learning Path takes you through the basics of Ceph all the way to gaining in-depth understanding of its advanced features. You’ll gather skills to plan, deploy, and manage your Ceph cluster. After an introduction to the Ceph architecture and its core projects, you’ll be able to set up a Ceph cluster and learn how to monitor its health, improve its performance, and troubleshoot any issues. By following the step-by-step approach of this Learning Path, you’ll learn how Ceph integrates with OpenStack, Glance, Manila, Swift, and Cinder. With knowledge of federated architecture and CephFS, you’ll use Calamari and VSM to monitor the Ceph environment. In the upcoming chapters, you’ll study the key areas of Ceph, including BlueStore, erasure coding, and cache tiering. More specifically, you’ll discover what they can do for your storage system. In the concluding chapters, you will develop applications that use Librados and distributed computations with shared object classes, and see how Ceph and its supporting infrastructure can be optimized.
By the end of this Learning Path, you'll have the practical knowledge of operating Ceph in a production environment.
