  Probe to calculate latency and free space in a file system
  
    vovfsprobe type name testdir period [OPTIONS]
  
  WHERE:
     type            Just a descriptive string (e.g. ISILON, NETAPP, GENERIC);
                     It does not affect the behavior of the probe.
     name            The nickname given to the filesystem;
                     It is used in naming the metrics.
     testdir         The full path to a writable directory in the filer.
     period          How often the test is run (e.g. 20s, 1m, 4m )
  
  
  OPTIONS:
     -v              -- Increase verbosity
  
  OPTIONS TO AFFECT LATENCY PROBE::
     -sz SZ          -- Change size of test file (default 32k)
     -r  N           -- Number of repetitions    (default 1)
  
  The probe creates  metrics:
     Filer=NAME/Latency             in ms
     Filer=NAME/LatencyLowPass      in ms
     Filer=NAME/FreeMB              in MB
     Filer=NAME/UsedMB              in MB
  This probe never stops. 
  
  
  EXAMPLES:
    % vovfsprobe ISILON IS1 /remote/ifstest/ttt  30s
    % vovfsprobe ISILON IS1 /remote/ifstest/ttt  30s -sz 100000 -r 10
