Went into "kibana" / "add data" and checked for data from a few metrics. Some appear to be working (EG system, k8) while others (EG kafka, elastic) (despite having data in dashboards, etc) show here as "no data received".
EG: elasticsearch. I go to my elastic host and check:
[root@myhost ~]# metricbeat modules list Enabled: elasticsearch kibana logstash system
Did I miss a step somewhere?
