            "content": "The cifsiostat command displays statistics about read and write operations on  CIFS  filesys‐\ntems.\n\nThe interval parameter specifies the amount of time in seconds between each report. The first\nreport  contains  statistics for the time since system startup (boot). Each subsequent report\ncontains statistics collected during the interval since the previous report.  A  report  con‐\nsists  of a CIFS header row followed by a line of statistics for each CIFS filesystem that is\nmounted.  The count parameter can be specified in conjunction with the interval parameter. If\nthe count parameter is specified, the value of count determines the number of reports  gener‐\nated  at interval seconds apart. If the interval parameter is specified without the count pa‐\nrameter, the cifsiostat command generates reports continuously.\n\n",
