eBPF holds the potential for true automatic instrumentation for observability. OpenTelemetry eBPF Instrumentation (OBI) is a new addition to the OpenTelemetry project, which brings the promise of a multi-language, multi-protocol auto-instrumentation, thanks to a code donation by Grafana Labs.

Our guest today is Mario Macías, Principal Software Engineer at Grafana Labs and OpenTelemetry eBFP Instrument maintainer. Macías joins Horovits to share about OBI, its origins, capabilities and how it fits into the broader OpenTelemetry project.

Mario holds a Ph.D. in Computer Architecture and for the last 8 years he's been working in observability at different companies. He also authored books in Spanish language, such as "Programación en Go" or "Introducción a Apache Spark".
