Step-by-Step Setup of ELK for NetFlow Analytics

ELK is a very open source, useful and efficient analytics platform, and we wanted to use it to consume flow analytics from a network. The reason we chose to go with ELK is that it can efficiently handle lots of data and it is open source and highly customizable for the user’s needs. The flows were exported by various hardware and virtual infrastructure devices in NetFlow v5 format. Then Logstash was responsible for processing and storing them in Elasticsearch. Kibana, in turn, was responsible for reporting on the data. Given that there were no complete guides on how to use NetFlow with ELK, below we present a step-by-step guide on how to set up ELK from scratch and enabled it to consume and display NetFlow v5 information.
