In the above demonstration, we run nfswizard.d for several seconds then hit
Ctrl-C. The report contains useful information about NFS client activity,
including response time statistics and file access details.
Note: this is measuring activity caused by NFS client processes (which must
be on the same server). It is not examining NFS server processes.
