Does a health check concern a whole node or does it concern individual containers?

I have created my LoadBalancer service with kubectl create -f web-service.yaml:

apiVersion: v1
kind: Service
metadata:
  name: reaction-prod
  labels:
    name: reaction-prod
    app: reaction-prod
spec:
  type: LoadBalancer
  loadBalancerIP: xxx.xxx.xxx.xxx
  ports:
    - port: 80
      targetPort: 80
      protocol: TCP
  selector:
    name: reaction-prod
    app: reaction-prod

The load balancer targets a port inside the running containers, I have learned by experiment. If I add a health check to that load balancers target pool, does it automatically do the same? I found no way to configure that or get information about what it is doing.

How can I get statistics on that health check?

gcloud compute http-health-checks describe doesn't really give me much useful info.

As explained here, the health checks of the Load Balancer are different from Kubernetes’ health checks. That being said, a friendly way to monitor your PODs in GKE is by using Stackdriver Monitoring.
