Hi I am using filebeat to save netflow data in elasticsearch. But while going through the data I realized there is no netflow sequence number stored in the index. Although when I use old version of logstash I get the sequence number in the index.Can anyone help me why this field is not generating or how to generate this field because using sequence number we can detect anomalies in the netflow logs
