Hello,  
I'm trying to extract some field/value pairs from a single field in a json string. My sample message:  
{  
...  
"comment":"Ticket number : INC:I16393898, status : Work In Progress, group : Ent.Support.SOC.",  
...  
}

From the value of the "comment" field I would like to extract three separate field/value pairs:  
"Ticket number":"INC:I16393898"  
"status":"Work In Progress"  
"group":"Ent.Support.SOC."

What I tried and miserably failed:  
filter {  
mutate {  
add\_field =\> { "cmt\_ticket\_no" =\> "%{[comment][Ticket number]}" }  
add\_field =\> { "cmt\_status" =\> "%{[comment][status]}" }  
add\_field =\> { "cmt\_group" =\> "%{[comment][group]}" }  
}}  
Is there a solution for what I try to achieve? Any suggestion is highly appreciated. Thanks.

Hi

Take a look at the `kv{}` filter [here](https://www.elastic.co/guide/en/logstash/current/plugins-filters-kv.html).

I think you can easily extract what you need using `source` and `field_split` or `field_split_pattern` in the `kv{}`filter.

Hope this helps.
