What does this have that CloudWatch enhanced metrics doesn't? From the screenshots, the metrics look pretty similar. Not a slight at all against this project (it looks awesome), I'm just curious if your infrastructure is already AWS based what would cause you to choose a non-CloudWatch option.
CloudWatch charges you per instance if you want 1 minute metrics instead of the standard (free) 5 minute metrics. Any tool that collects the data for you gets you out of that $3.50/instance/month detailed monitoring charge [1].
It's one second metrics, and has been designed to allow us to add other metric sources and visualizations (using, say, ftrace, perf_events, SystemTap, etc), although those are not in the initial release.
It looks like it has some metrics that aren't present in cloudwatch without a lot of scripting, such as Memory utilization. I'm new to cloud watch though, so someone please correct me if that is wrong.
