A year down the road from this article by Felix Barnsteiner
do you believe that it would be a good idea to transfer all our collectd data to elasticsearch instead of using graphite, whisper and carbon-cache?
ElasticSearch is new for us and we plan to use it for the logging of our 1000 Linux servers, but we
could also migrate all of our collectd data to ES at the same time.
We tried using Grafana 4.1.3 to query basic metrics stored in ES (lucene syntax) and quickly realized
that it would be a big job (if even possible) to transform all of our Grafana dashboards built using graphite to ElasticSearch.
That is probably why there are no examples of this in the dashboard collection
available on your site.
We are seeking a professional opinion before moving in that direction.
