Properties
- balancingMode ↔ String?
-
Specifies how to determine whether the backend of a load balancer can
handle additional traffic or is fully loaded.
getter/setter pair
- capacityScaler ↔ double?
-
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).
getter/setter pair
-
customMetrics
↔ List<
BackendCustomMetric> ? -
List of custom metrics that are used for CUSTOM_METRICS
BalancingMode.
getter/setter pair
- description ↔ String?
-
An optional description of this resource.
getter/setter pair
- failover ↔ bool?
-
This field designates whether this is a failover backend.
getter/setter pair
- group ↔ String?
-
The fully-qualified URL of aninstance
group or network endpoint
group (NEG) resource.
getter/setter pair
- hashCode → int
-
The hash code for this object.
no setterinherited
- maxConnections ↔ int?
-
Defines a target maximum number of simultaneous connections.
getter/setter pair
- maxConnectionsPerEndpoint ↔ int?
-
Defines a target maximum number of simultaneous connections.
getter/setter pair
- maxConnectionsPerInstance ↔ int?
-
Defines a target maximum number of simultaneous connections.
For usage guidelines, seeConnection
balancing mode and Utilization
balancing mode.
getter/setter pair
- maxInFlightRequests ↔ int?
-
Defines a maximum number of in-flight requests for the whole NEG or
instance group.
getter/setter pair
- maxInFlightRequestsPerEndpoint ↔ int?
-
Defines a maximum number of in-flight requests for a single endpoint.
Not available if backend's balancingMode is RATE
or CONNECTION.
getter/setter pair
- maxInFlightRequestsPerInstance ↔ int?
-
Defines a maximum number of in-flight requests for a single VM.
Not available if backend's balancingMode is RATE
or CONNECTION.
getter/setter pair
- maxRate ↔ int?
-
Defines a maximum number of HTTP requests per second (RPS).
getter/setter pair
- maxRatePerEndpoint ↔ double?
-
Defines a maximum target for requests per second (RPS).
getter/setter pair
- maxRatePerInstance ↔ double?
-
Defines a maximum target for requests per second (RPS).
getter/setter pair
- maxUtilization ↔ double?
-
Optional parameter to define a target capacity for theUTILIZATION
balancing mode.
getter/setter pair
- orchestrationInfo ↔ BackendBackendOrchestrationInfo?
-
Information about the resource or system that manages the backend.
getter/setter pair
- preference ↔ String?
-
This field indicates whether this backend should be fully utilized before
sending traffic to backends with default preference.
getter/setter pair
- runtimeType → Type
-
A representation of the runtime type of the object.
