gcloud alpha compute backend-services get-health - get backend health statuses from a backend service

gcloud alpha compute backend-services get-health BACKEND_SERVICE_NAME [--global     | --region=REGION] [--filter=EXPRESSION] [--limit=LIMIT] [--page-size=PAGE_SIZE] [--sort-by=[FIELD,…]] [--uri] [GCLOUD_WIDE_FLAG …]

If a group contains names of instances that don't exist or instances that haven't yet been pushed to the load-balancing system, they will not show up. Those that are listed as HEALTHY are able to receive load-balanced traffic. Those that are marked as UNHEALTHY are either failing the configured health-check or not responding to it.

Since the health checks are performed continuously and in a distributed manner, the state returned by this command is the most recent result of a vote of several redundant health checks. Backend services that do not have a valid global forwarding rule referencing it will not be health checked and so will have no health status.

BACKEND_SERVICE_NAME

Name of the backend service to operate on.

At most one of these can be specified:

--global

If set, the backend service is global.

--region=REGION

Region of the backend service to operate on. Overrides the default compute/region property value for this command invocation.

--filter=EXPRESSION

Apply a Boolean filter EXPRESSION to each resource item to be listed. If the expression evaluates True, then that item is listed. For more details and examples of filter expressions, run $ gcloud topic filters. This flag interacts with other flags that are applied in this order: --flatten, --sort-by, --filter, --limit.

--limit=LIMIT

Maximum number of resources to list. The default is unlimited. This flag interacts with other flags that are applied in this order: --flatten, --sort-by, --filter, --limit.

--page-size=PAGE_SIZE

Some services group resource list output into pages. This flag specifies the maximum number of resources per page. The default is determined by the service if it supports paging, otherwise it is unlimited (no paging). Paging may be applied before or after --filter and --limit depending on the service.

--sort-by=[FIELD,…]

Comma-separated list of resource field key names to sort by. The default order is ascending. Prefix a field with ``~´´ for descending order on that field. This flag interacts with other flags that are applied in this order: --flatten, --sort-by, --filter, --limit.

--uri

Print a list of resource URIs instead of the default output, and change the command output to a list of URIs. If this flag is used with --format, the formatting is applied on this URI list. To display URIs alongside other keys instead, use the uri() transform.

Run $ gcloud help for details.
