The Parser

We will create a parser that will take the single numbers in and create a message with a field called value in them using the CSVParser.

Add the following file to $METRON_HOME/config/zookeeper/parsers/mad.json:

{
  "parserClassName" : "org.apache.metron.parsers.csv.CSVParser"
 ,"sensorTopic" : "mad"
 ,"parserConfig" : {
    "columns" : {
      "value_str" : 0
                }
                   }
 ,"fieldTransformations" : [
    {
    "transformation" : "STELLAR"
   ,"output" : [ "value" ]
   ,"config" : {
      "value" : "TO_DOUBLE(value_str)"
               }
    }
                           ]
}
