describe-target-group-attributes

Description

Describes the attributes for the specified target group.

For more information, see Target Group Attributes in the Application Load Balancers Guide or Target Group Attributes in the Network Load Balancers Guide .

See also: AWS API Documentation

See 'aws help' for descriptions of global parameters.

Synopsis

  describe-target-group-attributes
--target-group-arn <value>
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]

Options

--target-group-arn (string)

The Amazon Resource Name (ARN) of the target group.

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI 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.

--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. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.

Examples

          "Value": "false",
          "Key": "stickiness.enabled"
      },
      {
          "Value": "300",
          "Key": "deregistration_delay.timeout_seconds"

Output

Attributes -> (list)

Information about the target group attributes

(structure)

Information about a target group attribute.

Key -> (string)

The name of the attribute.

The following attributes are supported by both Application Load Balancers and Network Load Balancers:

  • deregistration_delay.timeout_seconds - The amount of time, in seconds, for Elastic Load Balancing to wait before changing the state of a deregistering target from draining to unused . The range is 0-3600 seconds. The default value is 300 seconds.

The following attributes are supported by only Application Load Balancers:

  • slow_start.duration_seconds - The time period, in seconds, during which a newly registered target receives a linearly increasing share of the traffic to the target group. After this time period ends, the target receives its full share of traffic. The range is 30-900 seconds (15 minutes). Slow start mode is disabled by default.
  • stickiness.enabled - Indicates whether sticky sessions are enabled. The value is true or false . The default is false .
  • stickiness.type - The type of sticky sessions. The possible value is lb_cookie .
  • stickiness.lb_cookie.duration_seconds - The time period, in seconds, during which requests from a client should be routed to the same target. After this time period expires, the load balancer-generated cookie is considered stale. The range is 1 second to 1 week (604800 seconds). The default value is 1 day (86400 seconds).

The following attributes are supported by only Network Load Balancers:

  • proxy_protocol_v2.enabled - Indicates whether Proxy Protocol version 2 is enabled. The value is true or false . The default is false .

Value -> (string)
