I've been testing an ELK stack setup with metric beats for monitoring and have noticed odd behaviour. If I upgrade metricbeats to 6.5.1 from the elastic.co repos in Ubuntu then the data is still shipped to my logstash/elastic instances and I can view the data manually in discover but the Metricbeat System overview dashboard along with the kibana built in filter/search boxes no longer see the host. Its like the index created by this version (as I'm using the default logstash config where it uses metricbeat-$version and date fields) is causing some issue with Kibana's built in filtering.
I don't know if this is more an issue for Kibana however I thought i'd start with the data pusher rather than the visualisation board.
Thanks for the assistance in advance!
