Field

Description

target_states[]

TargetState

Target states of the specified target group.

TargetState

A target state resource.

Field

Description

status

HealthcheckStatus

Health of the target, i.e. its statuses in all availability zones.

target

status

enum Status

Status of the target in the availability zone.

failed_active_hc

bool

Indicates whether the target has been marked UNHEALTHY due to failing active health checks,
which determine target statuses as configured in HttpBackend.healthchecks or GrpcBackend.healthchecks.

Currently the only type of health checks is active, as described above.
Passive health checks, which determine the health of a target based on its responses to production requests
(HTTP 5xx status codes, connection errors etc.), are not implemented yet.

Target

A target resource.
For details about the concept, see documentation.

If set, will not require subnet_id to validate the target.
Instead, the address should belong to one of the following ranges:
10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16
Only one of subnet_id or private_ipv4_address should be set.
