Hello,

The following logstash conf file should send back the content of a sftp server. But I get an empty message in the created index.  
When my command is "DIR C:/Logs", I can get some informations in the message. Is there something wrong with this command ?

input {  
exec {  
command =\> "curl -k -v sftp://user:password@host.fr"  
interval =\> 30000  
}  
}

output {

```
elasticsearch {
	hosts => "localhost:9200"
	index => "test_exec"
	
}	
stdout {
	codec => dots
}

```

}

Regards,

Nicolas
