Hello,  
I am testing to get the all the data in .CSV file and unable to get the all the fields and nested in the.CSV file,My config file as below  
input {  
stdin {}  
beats {  
port =\> 5044  
}  
}

output {  
csv {  
#fields =\> ["@timestamp","message","version","architecture"]  
fields =\> ["@timestamp","event.dataset","host.mac","host.hostname","host.os.name","host.ip","log.file.path","message","service.type"]  
path =\> "/tmp/excel/syslogout.csv"  
}  
}

If i run this i will get the only fields @timestamp and message in my syslogout.csv output file.

Hi,

In the csv output plugin documentation, you can read this about the fields option :  
`If a field does not exist on the event, an empty string will be written. Supports field reference syntax eg: fields => ["field1", "[nested][field]"].`

So in your case, to take into account nested fields, your fields option should be like this :

```auto
fields => ["@timestamp","[event][dataset]","[host][mac]","[host][hostname]","[host][os][name]","[host][ip]","[log][file][path]","message","[service][type]"]

```

If the result does not change, it means that your nested fields do not exist.

Cad.
