Kind regards

Thats the netflow part of my config in /etc/logstash/conf.d
```
input {
udp {
port => XXX
type => netflow
codec => netflow
}
}
output {
if ( [type] == "netflow" ) {
elasticsearch {
hosts => ["XXX:9200"]
index => "netflow-%{+YYYY.MM.dd}"
user => XX
password => XX
}
}
}
```
I am using the elk version 5.6.1
The logstash-output-elasticsearch plugin is 7.4.1
