Instrumenting legacy or closed sourced applications can be a pain. But it doesn't have to be! This talk offers an introduction to the open source Beyla tool and shows you how to utilize it in order to instrument different types of applications without touching a single line of code. Beyla hooks into the kernel using eBPF and does the hard work for you. It's not only useful for services where you can't influence the underlying instrumentation, but it can help you establish a baseline level of observability in large scale deployments. We’ll also go over limitations, so you’ll leave the talk knowing if Beyla is right for you (spoiler: it probably is).

Dominik started his journey in technology as an SRE, working on projects ranging from warehouse logistics and photobook designers to analyzing satellite imagery. During this time, he discovered his passion for developer tooling and making sure developers can focus on what they do best - build great software! Now he is working as a Developer Experience Engineer at Grafana Labs, building tools to see clearly in the ever-changing world of software.
