The ability to create custom dashboards from multiple sources of information, such as logs or metrics collected by other tools like Prometheus/Grafana etc., was one thing that I liked best about this product! This feature alone has saved me hours every time we have had issues with our production systems - it's been invaluable in troubleshooting problems quickly so they don't end up being much more than "oops" moments (which are always bad!).
One piece missing here would be some formality around how often you can see your dashboard updated after creating them; there doesn’t seem any way currently aside perhaps running jobs manually via cron script? Also maybe consider adding support for Grafana 3+ which will allow greater integration between these products too :) As mentioned above though all-inclusive Dashboard creation toolkit makes life easier when trying out new things without needing extensive training first ;).
