I am capturing netflow packets and displaying the information on kibana dashboard .I am able to do so but around 30-40 % packets are being dropped . I am verfiying the packets in tcp dump and the some packets not able to see in kibana .

I have created following pipeline : Filebeat \>\>\>logstash \>\>Elastic .

Following is the Filbeat's netflow configuration .

netflow.yml

- module: netflow  
log:  
enabled: true  
var:  
netflow\_host: 0.0.0.0  
netflow\_port: 2055  
queue\_size: 8192

I see dropped packets in filbeat log

```auto
