Write on Fibre ports

Hi,

While looking at WLA data on Fibre port in the matrix tab,I have throughput in KB but i would like to see number writes per the Fibre ports.Is there any way to check the info?

Secondly some what related,Can i combine the number of Fibre ports to see the total throughput or write utilization like was for the devices.While i am choosing bunch of devices it displays all devices in the graph but not combined?is there any way....Thanks in advance.
