+Optional. Specifies the range of lines for identifying a file. The valid values are one number or two dash delimited numbers, such as '1', '2-5'. The default value is '1' so the first line is used to calculate fingerprint.  Fingerprint lines are not sent to CloudWatch Logs unless all the specified lines are available.
