Methods
__construct
Constructor.
data
array
Optional. Data for populating the Message object.
↳ 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. 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.
↳ 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 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.
↳ description
string
An optional description of this resource. Provide this property when you create the resource.
↳ failover
bool
This field designates whether this is a failover backend. More than one failover backend can be configured for a given BackendService.
↳ group
string
The fully-qualified URL of an instance 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 with https://www.googleapis.com/ ) to specify the instance group or NEG. Partial URLs are not supported.
↳ max_connections
int
Defines a target maximum number of simultaneous connections. For usage guidelines, see Connection balancing mode and Utilization balancing mode. Not available if the backend's balancingMode is RATE.
↳ max_connections_per_endpoint
int
Defines a target maximum number of simultaneous connections. For usage guidelines, see Connection balancing mode and Utilization balancing mode. Not available if the backend's balancingMode is RATE.
↳ max_connections_per_instance
int
Defines a target maximum number of simultaneous connections. For usage guidelines, see Connection balancing mode and Utilization balancing mode. Not available if the backend's balancingMode is RATE.
↳ max_rate
int
Defines a maximum number of HTTP requests per second (RPS). For usage guidelines, see Rate balancing mode and Utilization balancing mode. Not available if the backend's balancingMode is CONNECTION.
↳ max_rate_per_endpoint
float
Defines a maximum target for requests per second (RPS). For usage guidelines, see Rate balancing mode and Utilization balancing mode. Not available if the backend's balancingMode is CONNECTION.
↳ max_rate_per_instance
float
Defines a maximum target for requests per second (RPS). For usage guidelines, see Rate balancing mode and Utilization balancing mode. Not available if the backend's balancingMode is CONNECTION.
↳ max_utilization
float
Optional parameter to define a target capacity for the UTILIZATION balancing mode. The valid range is [0.0, 1.0]. For usage guidelines, see Utilization balancing mode.
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.
