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}}}}
