DNS Tracing & Metrics Via eBPF in OpenTelemetry- Endre Sara, Causely & Nikola Grcevski, Grafana Labs

This talk explores the integration of DNS observability into the OpenTelemetry eBPF Instrumentation (OBI) agent, addressing the critical role DNS resolution plays in modern cloud native applications. The speakers, Endre Sara from Causely and Nikola Grcevski from Grafana Labs, discuss architectural challenges such as eBPF context, semantic conventions, and scalability. They also present a proposed metrics and tracing model that enhances operators' ability to diagnose DNS performance issues, which often go unnoticed amidst network noise. Attendees will gain insights on instrumenting low-level system interactions and receive a blueprint for enhancing eBPF agent observability.
