I know this feels like beating a dead horse a little bit (I've searched this topic a lot in the forums but have yet to find an answer)....but this has really got me stumped.
I had ElasticSearch and Kibana running with WinlogBeat and Heartbeat sending data to Elasticsearch for about 2 days. I had the index Pattern setup and the Heartbeat dashboard working.
I then install x-pack and they no longer show data.
I decided to delete both the winLogbeat-* and the heartbeat-* indexes from Kibana hoping to recreate them and now Kibana (under Management, Index Patterns) says "Couldn't find any Elasticsearch data".
I then uninstalled x-pack and I could recreate the indexes just fine. I feel like I'm missing a critical piece of the x-pack install/config.
Open to any suggestions.
