Systing helps you solve problems in minutes rather than days. Out of the box it gives you everything you could possibly need, combined with perfetto’s visualization you will never be confused again.
This talk will introduce systing, a tracer that is built on modern BPF tooling, purpose built to debug large applications with complicated interactions.
This will be little talk and mostly demo. Two decades of experience debugging kernel problems has been poured into this tool to make it as straightforward as possible. I will walk through the basic usage, and show a case study investigation to give a feel for the various features that set it apart from the lower level tools we all use and love.
I’m a long time kernel developer and fixer of difficult problems. I spent a lot of time as a maintainer of Btrfs and lead developer. I’ve worked in a variety of kernel areas to fix problems, and lately have been focusing my time on building systing, a tool to help me debug difficult issues.
