Comment 5 Pradeep Kilambi 2015-04-18 01:08:30 UTC

To verify this:

* spin up instances with volumes via cli or dashboard

* the metrics of interest are :

- disk.device.read.bytes.rate"
- "disk.device.read.requests.rate"
- "disk.device.write.bytes.rate"
- "disk.device.write.requests.rate"

These are already part of the pipeline.yaml and derived through transformers. So these are essentially derived metrics. So just make sure these meters show up via cli.

Let me know if you have any questions
