Description
Modern production systems often restrict SSH access, making traditional debugging on Ubuntu instances increasingly difficult. In this talk, I share real-world SRE experiences debugging live issues on Ubuntu virtual machines running on GCP, without logging into them.
Using eBPF-based tools on Ubuntu, I demonstrate how to trace system calls, analyze network behavior, and identify performance bottlenecks in real time. Through actual incident scenarios, we’ll uncover how Ubuntu’s kernel capabilities combined with eBPF enable “invisible debugging,” helping engineers resolve critical issues faster without disrupting production systems.

What audience can learn
Here’s a strong, reviewer-friendly answer:
Attendees will learn how to debug production issues on Ubuntu systems without relying on SSH access, using modern kernel-level observability techniques. They will gain a practical understanding of how eBPF works on Ubuntu and how it can be used to trace system calls, monitor network activity, and identify performance bottlenecks in real time. Through real incident examples on GCP-hosted Ubuntu instances, the audience will learn when and how to apply these techniques effectively. By the end, they will be equipped with actionable approaches to troubleshoot complex issues in a non-intrusive, production-safe manner.
