I've just installed Topbeat on a node and, of course, want to capture data and view it in Kibana. I do have it working (topbeat.yml configured to use logstash as output), but all the Topbeat data end up in the logstash-* indices. I'd like to get the Topbeat data into topbeat-* indices, but everything else into logstash-*. Can this be done? If so, I take it I have to set up it up in my logstash output configuration? How?
