I am generating a csv file by loading a log file from filebeat and using logstash to process the data specifying the input and output. The format of logstash output configuration is as follows.

```
output {
        csv {
     fields => ["fieldA","fieldB"]
            path => "/home/csv_reports/%{+YYYY}-%{+MM}-%{+dd}/myReport.csv"
       
        }
}

```

The data in the logfile is correctly loaded into the csv file without any problem displays in the 2 fields. But the header names are missing. How to resolve this issue.?

Thanks in advance.
