i tried to setup netflow logstash based on this tutorial :
Everything works fine except the kibana dashboards
I get a lot of errors like following
Visualize: Fielddata is disabled on text fields by default. Set fielddata=true on [netflow.dst_addr] in order to load fielddata in memory by uninverting the inverted index. Note that this can however use significant memory.
I am not sure if i did something wrong or the provided index is broken
