This document provides an overview and agenda for a presentation about Calico, applications profiling, and BPF observability. The presentation covers Calico networking and security, what applications are, how BPF and eBPF can provide monitoring and observability capabilities like iostat and top traditionally have, and a demo of these techniques. It encourages connecting on social media and lists additional resources for troubleshooting and learning more about Calico, eBPF, and related tools.
