This will return the index template:
curl http://localhost:9200/_template/winlogbeat?pretty
This will return the mapping used for today's index. The data types should match whats in the index template.
curl http://localhost:9200/winlogbeat-2016.08.09/_mapping?pretty
You can paste the data to http://pastebin.com and share the link because it's probably too big to post directly on here.
