The attached scripts allow you to leverage powershell to collect performance statistics from EMC Isilon storage arrays. Output options incldue PSObjects, CSV, and screen painting similar to linux top. All native statistics that are available via the "isi statistics" command are available.
See the script header and attached images for examples of running.
This must be something internal to how the stats are calculated by way of some Isilon internal logic. Possibly, each stat is calculated individually and the total can represent the individual components at different time slices. The scripts don't do any data manipulation.
I would have to forward this one to the Isilon group to see why the "isi statistics system --nodes -d" demonstrates what you see.

in screenshot 5, how come individual nodes stats do not add up to the number in All row ?
Thanks
