Asok Gems and How To Polish Them - Marcel Lauhoff, Clyso
The Ceph Admin Socket (`asok`) is a powerful diagnostic interface on every daemon, yet it remains an often overlooked feature. This presentation is a practical guide to using this interface for advanced system analysis.
In this session, we will explore the admin socket interface from the ground up to practical application. We will begin by examining how the interface works and present techniques for discovering and using its full range of commands. From there, we will focus on several high-value 'gems', showcasing the unique operational data they expose. Each example will serve as a case study for building effective tooling, demonstrating methods to parse, visualize, and ultimately act upon the information.
