Here’s how to get health status of a GCP Load Balancer Backend Services.
For all load balancers except target pool.
gcloud compute backend-services get-health BACKEND_SERVICE_NAME \ --region us-central1 \ --project project-id |
gcloud compute backend-services get-health BACKEND_SERVICE_NAME \ --region us-central1 \ --project project-id
For target pool load balancers, use this command.
gcloud compute target-pools get-health TARGET_POOL_NAME \ --region us-central1 \ --project project-id |
gcloud compute target-pools get-health TARGET_POOL_NAME \ --region us-central1 \ --project project-id
