This allows the user to + retrieve the data in several smaller files of the passed in size. This parameter is currently only + supported on the SN340 device. + +-e <OFFSET>:: +--offset=<OFFSET>:: + Specifies the data offset at which to start retrieving the data. This parameter is used in combination + with the file size parameter to retrieve the data in several smaller files. This parameter is currently + only supported on the SN340 device. + +-t <TYPE>:: +--type=<TYPE>:: + Specifies the telemetry type - NONE, HOST, or CONTROLLER. This parameter is used to get either the host + generated or controller initiated telemetry log page. If not specified or none is specified, the command + will return the default E6 log data.
