How to create vscsiStats output:

Connect via SSH to your ESXi Host Obtain Virtual Machine worldGroupID:
# vscsiStats -l
Start collection
# vscsiStats -s -w 
Wait a couple of minutes and/or run your workload Write the current histograms to the disk:
#vscsiStats -p all -c -w  > /tmp/vscsistats.csv
Stop collection
#vscsiStats -x -w 
Your file should look like this:
Histogram: IO lengths of commands,virtual machine worldGroupID,4426,virtual disk handleID,8193 (scsi0:1)
