OpenTelemetry is expanding beyond the traditional “three pillars of observability” and introduces a groundbreaking addition to its signals - Continuous Profiling. The new Profiling Special Interest Group (SIG) that was formed to lead the topic has already made significant advancements, to be featured at KubeCon Europe. Join us in this special panel episode of OpenObservability Talks as we explore the significance of this new dimension in understanding application behavior, optimizing performance, and gaining deeper insights into your systems. Our expert guests, Felix Geisendörfer and Ryan Perry, members of the OpenTelemetry Profiling SIG, share their insights into how Profiling enhances the OpenTelemetry framework, and update on the work for open specification and implementation.
This special episode hosts a panel of two distinguished members of OpenTelemetry’s Profile SIG, and prominent members of the observability vendor ecosystem. Felix Geisendörfer is a Senior Staff Engineer at Datadog where he works on Continuous Profiling and contributes to the Go runtime. Before that he was working at Apple, co-founded Transloadit, contributed to node.js and inspired a generation of mad scientists to program flying robots with it. Ryan Perry is Principal Product Manager at Grafana Labs. He has built a career at various startups while actively contributing to open source projects and advancing open telemetry initiatives. Most recently he built Pyroscope, an open source continuous profiling project/company, which has been acquired by Grafana Labs.
