getBalancingMode()
public String getBalancingMode()
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. 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.
Check the BalancingMode enum for the list of possible values.
optional string balancing_mode = 430286217;
| Type | Description |
| String | The balancingMode.
|
getBalancingModeBytes()
public ByteString getBalancingModeBytes()
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.

optional string balancing_mode = 430286217;
| Type | Description |
| ByteString | The bytes for balancingMode.
|
getCapacityScaler()
public float getCapacityScaler()
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 on balancingMode). 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 than 0.1. 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 a balancingMode. This includes backends such as global internet NEGs, regional serverless NEGs, and PSC NEGs.
optional float capacity_scaler = 315958157;
| Type | Description |
| float | The capacityScaler.
