Hi All
What metric can help to find out VM's (windows os) that having issue with disk performance on OS level because of high disk queue (usually cased by low disk queue depth of the LSI Logic SAS driver).
Recently customer complained about but disk performance on Windows SQL server so we changed LSI Logic SAS driver with PVSCSI and performance on OS is much better but can't see big difference on VM metrics after that change.
Just would like to monitor metric that would be good indicator of OS driver queue depth issue.
Thanks
