I've had a quick look for metrics in Cloudwatch and couldn't see anything but forgive me if I missed it. I would like to know if it's possible to watch and EBS volume and add more when it is nearing capacity. Is this something I can do through cloudwatch or should I write something to do it from the server itself?

Amazon has no visibility into how full your file systems are. You could write a short script to run within your instances, though, that could report this information to CloudWatch using their custom metrics.

This is was I was expecting the answer to be, better start getting my hands dirty! – Jamie Taylor Oct 15 '12 at 14:09
Yup! Enjoy! :) Cloudwatch custom metrics are fairly simple to use. It shouldn't be too difficult. – EEAA Oct 15 '12 at 14:10
