Instance Attribute Details

#balancing_mode ⇒ String

Specifies how to determine whether the backend of a load balancer can handle additional traffic or is fully loaded. For usage guidelines, see Connection balancing mode. Backends must use compatible balancing modes. Backends of a backend service may use different balancing modes. For more information, see Supported balancing modes and target capacity settings and Restrictions and guidance for instance groups. Note: Currently, if you use the API to configure incompatible balancing modes, the configuration might be accepted even though it has no impact and is ignored. Specifically, Backend.maxUtilization is ignored when Backend.balancingMode is RATE. In the future, this incompatible combination will be rejected. Corresponds to the JSON property balancingMode

Returns:

  • (String)

def balancing_mode
  @balancing_mode
end

#capacity_scaler ⇒ Float

A multiplier applied to the backend's target capacity of its balancing mode. The default value is 1, which means the group serves up to 100% of its configured capacity (depending onbalancingMode). A setting of 0 means the group is completely drained, offering 0% of its available capacity. The valid ranges are 0.0 and [0.1,1.0]. You cannot configure a setting larger than 0 and smaller than0.1. You cannot configure a setting of 0 when there is only one backend attached to the backend service. Not available with backends that don't support using abalancingMode. This includes backends such as global internet NEGs, regional serverless NEGs, and PSC NEGs. Corresponds to the JSON property capacityScaler

Returns:

  • (Float)

#failover ⇒ Boolean Also known as: failover?

#group ⇒ String

The fully-qualified URL of aninstance group or network endpoint group (NEG) resource. To determine what types of backends a load balancer supports, see the Backend services overview. You must use the fully-qualified URL (starting withhttps://www.googleapis. com/) to specify the instance group or NEG. Partial URLs are not supported. If haPolicy is specified, backends must refer to NEG resources of type GCE_VM_IP. Corresponds to the JSON property group
