Explore the potential of zero-instrumentation monitoring using eBPF in this 25-minute conference talk from KubeCon + CloudNativeCon Europe 2023. Discover how eBPF technology can revolutionize observability in cloud-native ecosystems without the need for code instrumentation. Learn about system-wide eBPF agents that capture events from infrastructure and applications, eliminating the need for recompilation or redeployment. Gain insights into alternative methods for collecting metrics and understand the level of observability achievable without traditional instrumentation techniques. This presentation is ideal for developers and end-users of Kubernetes, Prometheus, Envoy, and other CNCF-hosted projects seeking efficient monitoring solutions.
