  The tool is simple wrapper around Storage Command Line Tool.
  It is intended to be run by Telegraf `exec` input module
  to collect metrics for Physical Drives (PD) and
  Virtual Drives (VD/RAID arrays) connected to LSI controllers
  known to Storage Command Line Tool (StorCLI). Actually it works
  as simple filter to normalize data it gets from StorCLI.
  It run StorCLI utility to get data from controller.
  The tool looks for StorCLI binary in the following directories:
    current directory
    /opt/MegaRAID/storcli
    $PATH 

  Tested with folowing RAID controllers:
    LSI 3108 MegaRAID
    Cisco 12G SAS Modular Raid Controller
  and
    Storage Command Line Tool Ver 1.03.11 Jan 30, 2013

  Limitations:
    only one controller is supported at the time
    --sample-config is broken
    must be run via `sudo`

    If you receive 65534 as disk state please open bug and provide
    example of storcli output

  Known issues:
