Metricbeat not showing pod cpu usage - elasticsearch

Question

i have a kubernetes with minikube in which i would like to get metrics via elasticsearch metricbeat. Almost all the metrics are showing less the cpu usage, which is always 0. Even when i'm running a pod with high cpu usage. Here are my yaml's what can i possibly be doing wrong?
