I have tried running the above logstash configuration. But it just doesn't print any column headers even after running it with a single logstash worker. Please help.

Hi

Off the top of my head, could it be a collision between giving column names in your filter and having `autodetect_column_names => true`?

If you keep it to false you can give the filter your own column names and use more than 1 worker.

You can check the documentation for the csv filter here: [https://www.elastic.co/guide/en/logstash/current/plugins-filters-csv.html](https://www.elastic.co/guide/en/logstash/current/plugins-filters-csv.html)

Just a thought.
