I am new to ELK and am experiencing some issues.  
I want to monitor the eduroam service logs (I believe most of you know this service), I created some variables in logstash but these variables do not appear in the kibana interface.

All help is welcome.  
graciously

Hi there, did you change your pipeline to add these fields after some data had already been ingested? If so, then you might need to tell Kibana to refresh the index pattern fields. Please see [https://www.elastic.co/guide/en/kibana/6.4/index-patterns.html#reload-fields](https://www.elastic.co/guide/en/kibana/6.4/index-patterns.html#reload-fields) for more info.
