Hi Erdinc,
This template gives you accurate instruction about how we put it together to work with Cloud Metrics. It is not exactly what you are asking for but since Heat is part of OpenStack I hope it can still be useful for you.
It is right you need a Rackspace account to follow the instruction on the blog post. Other than that, it is a software-as-a-service and can be used no matter where your infrastructure is. Grafana support from Cloud Metrics is in field testing. We can
discuss that topic off this thread about blueflood. Just let me know.
After we are done with our current release we can look into how that can be applied to blueflood itself. There is no ETA on that as far as I know.
