Input JSON file and change type of fields

[Jorge1 (Jorge)]

Hi,
I have a json file with a fixed structure and dynamic structure. In the fixed struture I changed the type of data using a template, this part is easy.

Logstash.conf

input {
  stdin {
    codec => json
    }
}
filter {
  date {
      match => [ "FECHA-OPRCN-F", "ISO8601", "YYYY-MM-dd HH:mm:ss" ]
      target => "FECHA-OPRCN-F"
      locale => "en"
    }
}

output {

stdout  {

codec => dots {}

}

elasticsearch {

index => "nginx_json_elastic_stack_example"

document_type => "logs"

template => "./nginx_json_template.json"

template_name => "nginx_json_elastic_stack_example"

template_overwrite => true

}

}

Template

{
  "template": "nginx_json_elastic_stack_example",
  "settings": {
     "index.refresh_interval": "5s"
  },
  "mappings": {
     "_default_": {        
        "properties": {
           "CANAL" : {
				"type" : "long"
			},
			"NUM-PARTICION-F" : {
				"type" : "long"
			},
			"COD-NRBE-EN-F" : {
				"type" : "long"
			},
			"COD-NRBE-EN-FSC-F" : {
				"type" : "long"
			},
			"COD-INTERNO-UO-F" : {
				"type" : "long"
			},
			"COD-INTERNO-UO-FSC-F" : {
				"type" : "long"
			},
			"COD-CSB-OF-F" : {
				"type" : "long"
			},
			"ID-INTERNO-EMPL-EP-F" : {
				"type" : "long"
			},
			"NUM-SEC-F" : {
				"type" : "long"
			},
			"FECHA-CTBLE-F" : {
				"type" : "date"
			},
			"VALOR-IMP-F" : {
				"type" : "double"
			},
			"VARIABLE": {
				"properties": {				  
				  "FECHA-CTBLE-F": {
					"type": "date"
				  }
				}
		    }
        },
        "_all": {
           "enabled": true
        }
     }
  }
}

But I have a problem in the dynamic structure, cause I need to change the type of data inside of "VARIABLE". This structure has many variables, I tried dynamic_templates like a API sample but it didnt work. I wonder if somone could help me, I need to change variables with numbers to numeric type (String->Numeric) in the dynamic structure.

static structure: all variables: NUM-PARTICION-F, NOMBRE-REGLA-F....VALOR-IMP-F, CANAL.
dynamic structure: VARIABLE {... all variables... }

Here I put three lines of me file:
