Hi,

I am trying to parse by logstash this:

```
"attributes": [
          {
            "value": "ValueA",
            "name": "NameA"
          },
          {
            "value": "ValueB",
            "name": "NameB"
          },
          {
            "value": "ValueC",
            "name": "NameC"
          }
        ],

```

To this:

```
"attributes": {
  "NameA": "ValueA",
  "NameB": "ValueB",
  "NameC": "ValueC"
}

```

Any recommendations?

I don't want to split this list to more records... The number of dictionaries and the values of name fields within them vary

You will need a ruby filter. Something similar to [this](https://discuss.elastic.co/t/logstash-adding-custom-field-to-documennt/139361/4).
