> In public clouds (and also private ones) it's important to know how much disk
> I/O each Instance is consuming.
> Today disk I/O is more expensive then RAM, CPU and Network bandwith, but
> CloudStack has no way of accounting this.
> CloudStack should collect the disk I/O statistics of all running instances so
> we can present these in the UI and in the Usage server
> The wiki page for this improvement:
> https://cwiki.apache.org/confluence/display/CLOUDSTACK/Disk+IO+statistics+for+instances
