git config --global credential.helper "cache --timeout=604800"

• Pods with highest CPU consumption (Prometheus Query)

topk(10, sum by (namespace, pod) (
  rate(container_cpu_usage_seconds_total{container!="",pod!=""}[5m])
))

• cluster-wide, sorted by current CPU (millicores)

kubectl top pod -A --sort-by=cpu
