Hi,

I manage to parse JSON array with logstash (Returns/Row)  
My configuration is

> ...  
> filter {  
> split {  
> field =\> "Returns[Row]"  
> add\_field =\> ["name" , "%{Returns.Row.name}"]  
> }  
> }  
> output {  
> stdout { codec =\> "rubydebug" }  
> }

But I get _Returns.row.xxx_ as output field name. So I try the _add field_ option wihtout success  
Any clue ?

Here is the output i get

> {  
> "Returns" =\> {  
> "Row" =\> {  
> "name" =\> "LOCAL.ESB.MONITORING\_ROUTER.AuditNotification",  
> "pendingMessageCount" =\> "106"  
> }  
> },  
> "@version" =\> "1",  
> "@timestamp" =\> "2015-10-23T16:25:54.534Z",  
> "name" =\> "%{Returns.Row.name}"  
> }  
> {  
> "Returns" =\> {  
> "Row" =\> {  
> "name" =\> "LOCAL.ESB.CORE\_AUDIT.LogEvent",  
> "pendingMessageCount" =\> "138"  
> }  
> },  
> "@version" =\> "1",  
> "@timestamp" =\> "2015-10-23T16:25:54.534Z",  
> "name" =\> "%{Returns.Row.name}"  
> }

Thanks for your help

What's this syntax supposed to mean? Do you mean `[Returns][Row]`?

> But I get Returns.row.xxx as output field name.

The field reference `Returns.Row.xxx` literally means "the field named Returns.Row.xxx", i.e. the following JSON snippet:

```
"Returns.row.xxx": { ... }

```

If the structure actually looks like

```
"Returns": {
  "Row": {
    "xxx": { ... }
  }
}

```

you need `[Returns][Row][xxx]`.

Hi Magnus,

Sorry for the late reply. It works fine with [Returns][Row] 😄  
Thank you for your help
