///The VisAO system monitor
/** Periodically queries various system temperatures and other parameters.  Makes use of some shell scripts to parse 
  * various /cat/proc and utility program outputs.  Temperatures are written to a TELEMETRY log.
  *
  * See \ref VisAOApp_standalone for command line arguments.  There are no additional command line arguments for sysmonD.
  *
  * This is a standalone VisAOApp, so it doesn't depend on MsgD.  In addition to the optional standard config options inherited from \ref VisAOApp_standalone this class has the following also optional config parameters:
  *    - <b>airTemp_serial_no</b> <tt>string</tt> - the serial number of the QTI temperature probe monitoring VisAO box air temp.
  *    - <b>joe47Temp_serial_no</b> <tt>string</tt> - the serial number of the QTI temperature probe monitoring little joe 47 
  *                                                   exhaust temp.
  *    - <b>qtiAmbSerialNo</b> <tt>string</tt> - the serial number of the QTI temperature probe monitoring ambient temp.
