Observing production workloads with enough detail to find real problems is difficult, but it's getting easier with the community adoption of eBPF. As the technology becomes better understood, tools like Falco, Cilium and Pixie are increasingly appearing in production clusters. But have you ever considered using eBPF data to help with unit tests, Continuous Integration and load testing? This talk will explain the basic technology behind eBPF while presenting some examples of how to use data collected via eBPF for a variety of software quality use cases. We'll use the Pixie CNCF sandbox project to pull data and replicate production issues on the developer desktop for debugging. You'll also get some ideas on using those calls in your Continuous Integration pipeline to sanity check builds before they are deployed. Included in that discussion will be handling some common issues like timestamp skew and authentication. All examples are open source and available after the talk.
