I suggest taking a look at the logz.io - it's essentially ELK as a service. We take care of many problems ES has and also have great features extra such as Alerting, Apps and Insights. I'm one of the core developers there so I'm fluent in pricing but last time I checked it's wasn't expensive and definitely worth your time and hosting costs. One the the great things about it is that you can simply migrate your dashboard and just ship to our Url.

What are you using? I'd rather run it myself, but like I said ELK was a bit too bleeding edge for me in the stability dept.

Heka for ingestion/parsing/message routing, RabbitMQ as the queuing/delivery mechanism, Elasticsearch as datastore, Grafana for visualization.
