Well, I have played with Splunk and the ELK (Elasticsearch - Logstash - Kibana) Stack for some thime now; review these interesting Pages and Blogs:
both somehow, that was not sufficient. Recently i "stumpled" upon Grafana, a Graphic frontend for several Datasouces, including Elasticsearch (ES) from version 4.1.
There is a fine installation guide, but due to the fact I did not want to "polude" my installation via the package system with "apt-get", i decided to get the tar file and unpack it into /data/grafana
This is absolutly excellent and the server spun up and I could start using ES as a datasource at once.
