61In the above demonstration, we run nfswizard.d for several seconds then hit
62Ctrl-C. The report contains useful information about NFS client activity,
63including response time statistics and file access details.

65Note: this is measuring activity caused by NFS client processes (which must
66be on the same server). It is not examining NFS server processes.
