Abstract
Ever wanted to ask arbitrary questions about your program while it is running with minimal impact on performance? In this talk, we go beyond static instrumentation and look at specific techniques for gathering information about your programs so that you can understand what your gophers are up to!
Ever had a bug that disappears when you go to debug it? Ever wanted to ask arbitrary questions about your program while it is running with minimal impact on performance? In this talk, we go beyond static instrumentation and look at specific techniques for gathering information about your programs so that you can understand what your gophers are up to!
Topics include:
•How to automate delve to gather data without impacting performance.
•What are uprobes and how to use them to instrument Go code.
•How to write eBPF programs with bpftrace and BCC to collect data about your programs.
•Injecting user space instrumentation code into your process using Frida.
This talk will expose you to tools and techniques for instrumenting live running Go programs. This will allow you to better understand the execution of your software and leave you better equipped to debug and improve your systems.
