How to auto create new hosts in Logentries for AWS EC2 autoscaling group

What's the best way to send logs from Auto scaling groups (of EC2) to Logentries.

I previously used the EC2 platform to create EC2 log monitoring for all of my EC2 instances created by an Autoscaling group. However according to Autoscaling rules, new instance will spin up if a current one is destroyed.

Now how do I create an automation for Logentries to create a new hosts and starting getting logs. I've read this http://ift.tt/1Fmq68n I'm stuck at the override['le']['pull-server-side-config'] = false since I don't know anything about Chef (I just took the training from their site)
