Creating an array of objects

Elastic Stack Logstash
1

Lets say in a given event i have 4 fields
psn1_name (holding the value "A",
psn1_age (holding the value 10,
psn2_name (holding the value "B",
psn2_age (holding the value 20.
I want to create a field person such that person is of the following structure

person = [
{
"name":"A"
,"age":10
},
{
"name":"B"
,"age":20
}
]

Can someone please suggest how to achieve this in the filter section of my logstash configuration.

Hmm. I'm not entirely sure that you can do this with a mutate filter. You may have to use a ruby filter and write a line or two of Ruby code.

Thanks. Looks like that is the only option
