You can create a scaling policy that uses the latency metric to help your Elastigroup respond when application response times increase. This helps your environment scale up when users experience delays.

1. In your Elastigroup configuration, go to the Scaling tab.

2. Under Simple scaling policies in the Up scaling policies section, select Add policy.

3. Configure the policy with the following settings:

   • Auto scale based on: Other

   • Namespace: Application ELB

   • Metric name: TargetResponseTime

   • Dimensions:

     • Name: LoadBalancer

     • Value: Enter the ARN of your load balancer like so:

       loadbalancer/app/{load-balancer-name}/{xxxxxxxxxxx}

4. Select Next and complete the remaining scaling policy options.
