vScsiStats Grapher creates dynamic charts from a csv based vscsiStats output. Paste the histogram output into the textbox or upload the entire file.
If you want to test the tool you can download sample.csv
Note: The output does not contain any sensitive information. Feel free to check the output prior to upload.
How to create vscsiStats output:
Connect via SSH to your ESXi Host Obtain Virtual Machine worldGroupID:# vscsiStats -lStart collection
# vscsiStats -s -wWait a couple of minutes and/or run your workload Write the current histograms to the disk:
#vscsiStats -p all -c -wStop collection> /tmp/vscsistats.csv
#vscsiStats -x -wYour file should look like this:
