Description

While doing disk IOPS / network benchmarking on some VM's we notice that the storage and network charts in Sunstone (Storage: (Disk read bytes,
Disk write bytes, Disk read IOPS, Disk write IOPS), ) do not reflect the actual IO usage at all. Counters collected by probes on the hypervisor are getting correct values from libvirt (we double checked that) and are also correctly reported to oned frontend. It seems to be a query / visualiation issue.
