vscsiStats 3D surface graph part 3: Build your own!

Some people have asked me how to actually create the 3D graphs from the vcsiStats tool. I use a simple Excel sheet for this. Using the script I described in vscsiStats into the third dimension: Surface charts! , you can import the files outputted into excel and see the Excel chart instantaneously.

The vscsiStats tool is a very powerfull vSphere utility. It allows you to see virtual disk performance (such as latency, IOPS block sizes etc). The script I used in part 1 and in part 2 of this series will shoot multiple samples of these values right after each other, which you can then import into Excel to produce surface charts, like this one:
