How to find cpu and ram usage in Kubernetes deployment

My Kubernetes cluster is failing to deploy new applications with insufficient CPU on the cluster

After digging around rancher and kubectl I have found that I am using 5% of CPU, but Reserved 96% CPU.

This is due to wrongly configured values in my micro-services values.yaml

If there a way to find out how much the micro-services are using when idle and when at load

resources:
  requests:
    memory: {{ .Values.resources.requests.memory | quote}}
    cpu: {{ .Values.resources.requests.cpu | quote}}

  limits:
    memory: {{ .Values.resources.limits.memory | quote}}
    cpu: {{ .Values.resources.requests.cpu | quote}}

I have tried using kubectl to describe the node I am monitoring netdata, but that is real time and hard to gauge limits from that.

If anyone had suggestions, that would be great

The built in tool is kubectl top but this requires you have metrics-server running, which you probably do if you are using a hosted kube option but might not if running it yourself. Beyond that, Prometheus and tools like node-exporter and cadvisor can get you the data
