This was written to use as a check with Sensu, but could be modified for anything. The "check-beanstalk-health.rb" available in the sensu-plugins-aws package would hang up randomly and cause issues on our Sensu master, so I wrote a quick bash script instead. This assumes that you are running this from an AWS instance that has an IAM profile applied with proper permissions or is using the default profile you have setup on whatever box you are running from. It also assumes you have JQ installed.
