Using csv output plugin to store JSON field data. But there are no column names; wondering how to give names to columns or how to add header row.

You can use the csv\_options option on the csv output to tell it to add a header row, but since every row is written independently each one will have a header. That is, every other row of the output will be a header.

You may be able to write the header row to the output file before running logstash.
