Improvements to the Nagios Plugin: https://exchange.nagios.org/directory/Plugins/Operating-Systems/*-Virtual-Environments/Others/Check_AWS_CloudWatch_metrics/details
I only monitor auto scaling instances and would be nice to have an option to get cloudwatch metrics by autoscaling group. At a first glance it looks quiet easy to just modify ec2 static values but i might be wrong.
That's the first time I touch ruby so any advice would be appreciated.
