Available fields in kibana

Elastic Stack Kibana
1

Here is this entry in logstash.conf

mutate {
       split => ["message","Employee"]
       add_field => {"part1" =>"%{[message][0]}"}
       add_field => {"part2" =>"%{[message][1]}"}      
}


mutate {
       split => ["part2","#"]
       add_field => {"part2_1" =>"%{[part2][0]}"}
       add_field => {"part2_2" =>"%{[part2][1]}"}

}

This adds part1 , part2 , part2_1 and part2_2 fields in Kibana's Available field list.

But my requirement is to add only part2_2 field . rest of the fields are not required in Kibana.

What changes I should make here so that only part2_2 field is added in Kibana's Available field list.

Hello @volcano - Which version of the elastic stack are you running? Do you need those fields to be in elasticsearch aside from usage in Kibana?

I dont want field part1 to be pushed to elasticsearch and then to Kibana. I want only part2 to be pushed to elastic search and kibana.

I am worried about the syntax. I am changing this way

From this...

        mutate {
               split => ["message","Employee"]
               add_field => {"part1" =>"%{[message][0]}"}
               add_field => {"part2" =>"%{[message][1]}"}      
        }

To this

mutate {
       split => ["message","Employee"]
       part1 =>"%{[message][0]}"}
       add_field => {"part2" =>"%{[message][1]}"}      
}

look at part1 above . Is this correct syntax not to add the field? I am stuck at this spot.

I am using elastic search managed service in AWS . version 7.1.1

I wonder if the dissect filter would be simpler - https://www.elastic.co/guide/en/logstash/7.1/plugins-filters-dissect.html
