Hi friends

I have installed size mapping plugin and I added it to Kibana meta fields too

I could successfully enable "\_size" in Elasticsearch via bellow command and see the result in kibana

```auto
PUT logstash-2023-06-06
{
  "mappings": {
    "_size": {
      "enabled": true
    }
  }
} 

```

but I could just enable size field in a single upcoming index, how to enable \_size mapping in all of my upcoming indices and index template?  
should I add it in Kibana index template or elasticsearch?

You need to create an index template which matches the index names you will create in the future.

Something like this should work I think:

```auto
PUT _index_template/logstash-size
{
  "index_patterns": ["logstash-*"],
  "template": {
    "mappings": {
      "_size": {
        "enabled": true
      }
    }
  },
  "priority": 500
}

```

Note that this applies only to new indices.
