Locate json field with jsonpath (logstash)

Elastic Stack Logstash

I would use a ruby filter to find the right entry in the array:

    ruby {
        code => '
            begin
                a = event.get("[response][result][0][CHILDMONITORS][0][CHILDMONITORINFO]")
                a = a.select { |x| x["DISPLAYNAME"] == "TotalNodos" }
                event.set("someField", a[0]["CHILDATTRIBUTES"][0]["Value"])
            rescue
            end
        '
    }
