Interesting! I have never heard of Prometheus, that looks neat. For production we have Fluentd setup for exporting logs to our Elasticsearch logging cluster and we also use Kibana for creating dashboards and saving searches. We have found Fluentd works really nice with Ruby which is why we choose it over something like logstash.
We also use Fluentd rather than logstash in our logs stack.
Prometheus is a great tool, but it's not based on the logs. Your app has to provide an API from which Prometheus will grab your metrics to build real-time aggregated dashboards.

Prometheus + Graphana = graphing heaven. :)
