describe-load-balancer-attributes

Description

Describes the attributes for the specified load balancer.

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.

Synopsis

  describe-load-balancer-attributes
--load-balancer-name <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options

--load-balancer-name (string)

The name of the load balancer.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

See ‘aws help’ for descriptions of global parameters.

Examples

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

To describe the attributes of a load balancer

This example describes the attributes of the specified load balancer.

Command:

aws elb describe-load-balancer-attributes --load-balancer-name my-load-balancer

Output:

{
  "LoadBalancerAttributes": {
      "ConnectionDraining": {
          "Enabled": false,
          "Timeout": 300
      },
      "CrossZoneLoadBalancing": {
          "Enabled": true
      },
      "ConnectionSettings": {
          "IdleTimeout": 30
      },
      "AccessLog": {
          "Enabled": false
    }
  }
}

Output

LoadBalancerAttributes -> (structure)

Information about the load balancer attributes.

CrossZoneLoadBalancing -> (structure)

If enabled, the load balancer routes the request traffic evenly across all instances regardless of the Availability Zones.

For more information, see Configure Cross-Zone Load Balancing in the Classic Load Balancers Guide .

Enabled -> (boolean)

Specifies whether cross-zone load balancing is enabled for the load balancer.

AccessLog -> (structure)

If enabled, the load balancer captures detailed information of all requests and delivers the information to the Amazon S3 bucket that you specify.

For more information, see Enable Access Logs in the Classic Load Balancers Guide .

Enabled -> (boolean)

Specifies whether access logs are enabled for the load balancer.

S3BucketName -> (string)

The name of the Amazon S3 bucket where the access logs are stored.

EmitInterval -> (integer)

The interval for publishing the access logs. You can specify an interval of either 5 minutes or 60 minutes.

Default: 60 minutes

S3BucketPrefix -> (string)

The logical hierarchy you created for your Amazon S3 bucket, for example my-bucket-prefix/prod . If the prefix is not provided, the log is placed at the root level of the bucket.

ConnectionDraining -> (structure)

If enabled, the load balancer allows existing requests to complete before the load balancer shifts traffic away from a deregistered or unhealthy instance.

For more information, see Configure Connection Draining in the Classic Load Balancers Guide .

Enabled -> (boolean)

Specifies whether connection draining is enabled for the load balancer.

Timeout -> (integer)

The maximum time, in seconds, to keep the existing connections open before deregistering the instances.

ConnectionSettings -> (structure)

If enabled, the load balancer allows the connections to remain idle (no data is sent over the connection) for the specified duration.

By default, Elastic Load Balancing maintains a 60-second idle connection timeout for both front-end and back-end connections of your load balancer. For more information, see Configure Idle Connection Timeout in the Classic Load Balancers Guide .

IdleTimeout -> (integer)

The time, in seconds, that the connection is allowed to be idle (no data has been sent over the connection) before it is closed by the load balancer.

AdditionalAttributes -> (list)

Any additional attributes.

(structure)

Information about additional load balancer attributes.

Key -> (string)

The name of the attribute.

The following attribute is supported.

• elb.http.desyncmitigationmode - Determines how the load balancer handles requests that might pose a security risk to your application. The possible values are monitor , defensive , and strictest . The default is defensive .

Value -> (string)

This value of the attribute.
