Measuring CPU usage of eBPF programs with Inspektor Gadget
Inspektor Gadget uses eBPF to inspect Linux systems and can be especially helpful on Kubernetes clusters. One question often asked before using Inspektor Gadget in production is how much CPU and memory resources it uses. This question has been difficult to answer because there was no easy way to check the resource consumption of eBPF programs. Kubernetes has tools to measure CPU usage of pods (kubectl top, metrics-server, cAdvisor, see Kubernetes documentation ) but those tools don’t measure eBPF programs.
