Fields
name

string

Identifier. Name of the ServiceLbPolicy resource. It matches pattern projects/{project}/locations/{location}/serviceLbPolicies/{service_lb_policy_name}.
createTime

string (Timestamp format)

Output only. The timestamp when this resource was created.

Uses RFC 3339, where generated output will always be Z-normalized and uses 0, 3, 6 or 9 fractional digits. Offsets other than "Z" are also accepted. Examples: "2014-10-02T15:01:23Z", "2014-10-02T15:01:23.045123456Z" or "2014-10-02T15:01:23+05:30".
updateTime

string (Timestamp format)

Output only. The timestamp when this resource was last updated.

Uses RFC 3339, where generated output will always be Z-normalized and uses 0, 3, 6 or 9 fractional digits. Offsets other than "Z" are also accepted. Examples: "2014-10-02T15:01:23Z", "2014-10-02T15:01:23.045123456Z" or "2014-10-02T15:01:23+05:30".
labels

map (key: string, value: string)

Optional. Set of label tags associated with the ServiceLbPolicy resource.

An object containing a list of "key": value pairs. Example: { "name": "wrench", "mass": "1.3kg", "count": "3" }.
description

string

Optional. A free-text description of the resource. Max length 1024 characters.
loadBalancingAlgorithm

enum (LoadBalancingAlgorithm)

Optional. The type of load balancing algorithm to be used. The default behavior is WATERFALL_BY_REGION.
autoCapacityDrain

object (AutoCapacityDrain)

Optional. Configuration to automatically move traffic away for unhealthy IG/NEG for the associated Backend Service.
failoverConfig

object (FailoverConfig)

Optional. Configuration related to health based failover.

LoadBalancingAlgorithm

The global load balancing algorithm to be used.

Enums
LOAD_BALANCING_ALGORITHM_UNSPECIFIED The type of the loadbalancing algorithm is unspecified.
SPRAY_TO_WORLD Balance traffic across all backends across the world proportionally based on capacity.
SPRAY_TO_REGION Direct traffic to the nearest region with endpoints and capacity before spilling over to other regions and spread the traffic from each client to all the MIGs/NEGs in a region.
WATERFALL_BY_REGION Direct traffic to the nearest region with endpoints and capacity before spilling over to other regions. All MIGs/NEGs within a region are evenly loaded but each client might not spread the traffic to all the MIGs/NEGs in the region.
WATERFALL_BY_ZONE Attempt to keep traffic in a single zone closest to the client, before spilling over to other zones.

AutoCapacityDrain

Option to specify if an unhealthy IG/NEG should be considered for global load balancing and traffic routing.

JSON representation 
{
  "enable": boolean
}
Fields
enable

boolean

Optional. If set to 'True', an unhealthy IG/NEG will be set as drained. - An IG/NEG is considered unhealthy if less than 25% of the instances/endpoints in the IG/NEG are healthy. - This option will never result in draining more than 50% of the configured IGs/NEGs for the Backend Service.

FailoverConfig

Option to specify health based failover behavior. This is not related to Network load balancer FailoverPolicy.

JSON representation 
{
  "failoverHealthThreshold": integer
}
Fields
failoverHealthThreshold

integer

Optional. The percentage threshold that a load balancer will begin to send traffic to failover backends. If the percentage of endpoints in a MIG/NEG is smaller than this value, traffic would be sent to failover backends if possible. This field should be set to a value between 1 and 99. The default value is 50 for Global external HTTP(S) load balancer (classic) and Proxyless service mesh, and 70 for others.
