Hey nice idea- I am looking at building a dashboard style web app like yours. Have you used any frameworks here or rolled your own? - I am on mobile or id take a closer look myself.
The platform allows users to code and launch a container which gets data into the DB and from there everything else is abstracted. There is a generic API that can be used to request that data from DB without writing any code and then on frontend I am developing a library that helps me hook these generic endpoints to different visualizations that I want just like kibana or grafana.
So QuantaleCore is like an end to end replacement for Elasticsearch + Logstash + Kibana
My email is on my profile. Email me if you would like to discuss it more. I would be happy to give you a demo.
