Linux kernel provides building blocks for advanced debugging and tracing of applications as well as the kernel itself. Those mechanisms enable skilled developers to examine a running system and check for potential bugs and performance bottlenecks.
Skilled developers can use Linux kernel tracing mechanisms to explore and learn application and kernel behavior in a running environment and collect crucial events and statistics. Collected and analyzed information will help them understand various risks, bottlenecks and bugs in the system.
This workshop is intended for groups of advanced Linux developers who would benefit from the knowledge of kernel and application instrumentation based on the Linux kernel features.
