Hello. I've configured the elk stack and now I want to add netflow to logstash.
I've made the necessary configuration files and even edited the modules in logstash.yml to enable netflow.
However, I continue to get Timelion: Error: in cell #1: Elasticsearch index not found: netflow-*
and visualize: Error: in cell #1: Elasticsearch index not found: netflow-*
The following can be seen in the dashboard: No data is being shown.
Please tell me if I am missing something. Should I do something with Elastic search as well?
I binded netflow with 2055 port with the following command:
/usr/share/logstash/bin# ./logstash --modules netflow -M netflow.var.input.udp.port=2055 --path.settings=/etc/logstash
Sending Logstash's logs to /usr/share/logstash/logs which is now configured via log4j2.properties
