Hi,

I am using Acconts.json as a data file which is having different fields e.g firstName, lastName ,city etc but I am not able to get the same as different fields in kibana.  
Please suggest how to apply filters to get the data (in logstash config file).

Prateek

This is a Logstash question, not a Kibana question. Please edit your post and change its category.

You need to use the [json codec](https://www.elastic.co/guide/en/logstash/current/plugins-filters-json.htmlhttps://www.elastic.co/guide/en/logstash/current/plugins-codecs-json.html) or [json filter](https://www.elastic.co/guide/en/logstash/current/plugins-filters-json.html) to parse the contents of the `message` field as JSON.

Adding codec =\> "json" within input{} helped to get the fields.

Regards.
