Hi folks,

I am new to ELK stack and trying to setup netflow module in logstash:

command line command : bin/logstash --modules netflow --setup -M netflow.var.input.udp.port=2055 -M netflow.var.elasticsearch.hosts="localhost:9200" -M netflow.var.kibana.host="10.62.xx.xxx:5601" -M "netflow.var.elasticsearch.username=xxxxx" -M "netflow.var.elasticsearch.password=xxxxx"

Getting following error:
