Hi, I have a running implementation of the ELK stack (6.X), with elastiflow module configured (with Elastiflow Dashboard configured on Kibana). I however get the following error on running logstash. The netflow logs are coming directly from network devices (routers) that are on the local network. I have read a number of threads concerning this issue, and they all seem to attribute this problem to the logstash-codec-netflow codec,and its tendency to assign the same Template ID (in this case 256). I have updated the 'logstash-codec-netflow' , but that seems not to solve the problem. Any ideas on how to resolve this issue?
