1.找目前硬碟 dmesg | grep hd
測試讀取 hdparm -Tt /dev/sda
time dd if=/mnt/home/testfile of=/dev/null bs=16k
/vscsiStats -l
Virtual Machine worldGroupID: 1076,
Virtual Machine Display Name: w2k3-ex01-64bit {
Virtual SCSI Disk handleID: 8195
Virtual SCSI Disk handleID: 8196
Virtual SCSI Disk handleID: 8197
}
1076 就是我们要的WID，8195~8197分别对应了每一个的SCSI控制器，要具体看是哪一个，要么猜，要么去esxtop的v页面，展开看scsi id那一项
/usr/lib/vmware/bin/vscsiStats -p seekDistance
VBA脚本，转换CSV到chart 。建议在EXCEL 2007 。该脚本自动在工作表中生成图形，并且在目录下生成带图表的网页。
使用方法：用excel载入CSV文件，按ALT+F11，打开宏编辑器，粘贴下面的脚本，然后按F5执行即可。

‘Macro to process vmware vscsiStats data
‘written in and tested in Excel 2003
‘it will expect your data to be in column A and the histogram BINS to be in column B
‘it will create a number of chart-sheets
‘charts will be created on individual tabs. If you run
‘vscsistats -p all -w WID and you have lots of drives this can make for a large
‘and unwieldy spreadsheet. If you have lots of drives, I recommend that you
‘process drives seperately
