Key

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.
