Getting Information About Your Load Balancers Using AWS CLI
Getting General Information About Your Load Balancers
To get information about one or more load balancers, use the describe-load-balancers command following this syntax:
$ aws elb describe-load-balancers \
--profile YOUR_PROFILE \

--endpoint https://lbu.eu-west-2.outscale.com
This command contains the following attributes that you need to specify:
-
(optional)
profile
: The named profile you want to use, created when configuring AWS CLI. For more information, see Installing and Configuring AWS CLI. -
(optional)
load-balancer-names
: The name of one or more load balancers.If you do not specify any load balancer name, the request returns a description of all your load balancers.
-
endpoint
: The endpoint corresponding to the Region you want to send the request to.
The describe-load-balancers command returns the following elements:

Timeout
: The maximum waiting time for a response before considering the request as failed, in seconds. -
UnhealthyThreshold
: The number of consecutive failed requests to consider the instance as unhealthy.
-
-
VPCId
: The VPC ID for the load balancer, if any. -
BackendServerDescriptions
: Information about the backend instances. This element contains the following information for each backend instance:-
InstancePort
: The port on which backend instances are listening. -

AppCookieStickinessPolicies
: The name of the policy for application-controlled session stickiness. For more information, see Configuring Sticky Sessions for Your Load Balancers. -
OtherPolicies
: The names of the policies other than the stickiness policies.
-
-
LoadBalancerName
: The name of the load balancer. -
CreatedTime
: The date and time of creation of the load balancer. -
AvailabilityZones
: The ID of the Availability Zone in which the load balancer was created. -
Scheme
: The type of load balancer. For more information, see About Load Balancers > Load Balancer Types.
