Kibana 3 doesn’t have a great way to visualize the sources count overtime but it is possible to ask gently to your ElasticSearch db

So until SexiLog comes with Kibana 4, you can use the awesome head plugin to achieve this goal.

Just copy/paste the following query in the “Any Request” tab and check the “value” property:

{“aggs”:{“host_count”:{“cardinality”:{“field”:”hostname.raw”,”precision_threshold”:40000}}}}
