You can port forward a local port to Prometheus or the HTTP tracker by running:
  export POD_NAME=$(kubectl get pods --namespace {{ .Release.Namespace }} -l "app={{ template "fullname" . }}" -o jsonpath="{.items[0].metadata.name}")
  # Prometheus port
  kubectl port-forward $POD_NAME 8080:{{ $v := .Values.config.chihaya.prometheus_addr | split ":" }}{{ $v._1 }}
  # HTTP tracker port
  kubectl port-forward $POD_NAME 8080:{{ $v := .Values.config.chihaya.http.addr | split ":" }}{{ $v._1 }}
