Describe Load Balancers
autoscaling_describe_load_balancers | R Documentation |
This API operation is superseded by DescribeTrafficSources, which can describe multiple traffic sources types¶
Description¶
This API operation is superseded by describe_traffic_sources
, which
can describe multiple traffic sources types. We recommend using
describe_traffic_sources
to simplify how you manage traffic sources.
However, we continue to support describe_load_balancers
. You can use
both the original describe_load_balancers
API operation and
describe_traffic_sources
on the same Auto Scaling group.
Gets information about the load balancers for the specified Auto Scaling group.
This operation describes only Classic Load Balancers. If you have
Application Load Balancers, Network Load Balancers, or Gateway Load
Balancers, use the describe_load_balancer_target_groups
API instead.
To determine the attachment status of the load balancer, use the State
element in the response. When you attach a load balancer to an Auto
Scaling group, the initial State
value is Adding
. The state
transitions to Added
after all Auto Scaling instances are registered
with the load balancer. If Elastic Load Balancing health checks are
enabled for the Auto Scaling group, the state transitions to InService
after at least one Auto Scaling instance passes the health check. When
the load balancer is in the InService
state, Amazon EC2 Auto Scaling
can terminate and replace any instances that are reported as unhealthy.
If no registered instances pass the health checks, the load balancer
doesn't enter the InService
state.
Load balancers also have an InService
state if you attach them in the
create_auto_scaling_group
API call. If your load balancer state is
InService
, but it is not working properly, check the scaling
activities by calling describe_scaling_activities
and take any
corrective actions necessary.
For help with failed health checks, see Troubleshooting Amazon EC2 Auto Scaling: Health checks in the Amazon EC2 Auto Scaling User Guide. For more information, see Use Elastic Load Balancing to distribute traffic across the instances in your Auto Scaling group in the Amazon EC2 Auto Scaling User Guide.
Usage¶
Arguments¶
AutoScalingGroupName
[required] The name of the Auto Scaling group.
NextToken

100
and the maximum value is100
.

list(
LoadBalancers = list(
list(
LoadBalancerName = "string",
State = "string"
)
),
NextToken = "string"
)
