The conferences feature presentations from developers and end users of Kubernetes, Prometheus, Envoy, and all of the other CNCF-hosted projects.
Hubble - eBPF Based Observability for Kubernetes - Sebastian Wicki, Isovalent
Troubleshooting network issues in Kubernetes often requires deep insight into different layers of your stack. Hubble is a new open-source observability platform that aims to assist you in understanding what is going on in all layers of your Kubernetes network. Based on the Cilium CNI and the Linux kernel eBPF technology, it is able to obtain fine-grained visibility into network traffic and applications behavior, with low overhead and without having to modify applications. In this talk, you will get a introduction into Hubble, and the technologies that power it, the Cilium CNI and eBPF. You will be presented with practical examples of how Hubble can be used to interactively troubleshoot complex network issues. The talk will show how to write custom Hubble metrics which allow you to benefit from eBPF's superpowers without having to write or understand any kernel code.

impressive demo! Thank U

[@chrisjaimon9137]

Cool demo. Thanks

[@jamjamsimth]

can Hubble monitor the traffic on sriov? and traffic that use host based networking ( i.e traffic that does not use Kubernetes service )?

[@MrAbdouQuilani]

Thank you for this demo Is the use of Hubble independent from the use of Cilium as a CNI? I mean can we observe networking trafic between PODs while using another CNI plugin? (e.g. flannel or calico) Thank you in advance

[@AlviseVitturi]

No, Hubble is based on Cilium and eBPF

wow what a demo, just show slides
