| enter evaperf vd |
| displayed in CSV at five second intervals for a total of 30 seconds and is also written to |
| the capture.log file. |
| Limits virtual disk data collection to the specified virtual disks. You must enter at least one |
| virtual disk. You can also combine this modifier with |
