I am listening to a log file (which is a CSV file) using FileBeat and sending the data to elasticsearch instance. I am using the default configurations for FileBeat as well as elasticsearch. It works but my data is shown in elastic in a field called
"input_type": "log", "message": "1481250458524,263,dummy request 3,200,OK,Thread Group 2 2-2,text,true,,114,0,10,15,39,0,2", "offset": 143092,
How can I make it process message into different fields before sending it to elastic?
