La conférence

SystemTap is a tracing and debugging tool that allows you to instrument virtually any part of a GNU/Linux system dynamically without requiring explicit support from the targeted application.

If you ever had the need to add a printf() without rebuilding and restarting the application ; if you ever wanted to see a live fork/execve tree of your running system ; if you ever dreamed of running strace system-wide ; if you ever had the need to collect performance measurements of specific function calls on your live production system be it in kernel or userland, you should be interested in SystemTap.

This talk will describe the SystemTap architecture, how to get started and will show practical examples. We will discuss limitations, performance and safety as well as how it compares to other debugging and tracing tools.
