@robi I am not sure we understand each other completely. Perhaps I am not communicating this well, but allow me another attempt, please.
I am not seeking for New Relic to be made into a self-hosted app - That is exactly why this is NOT in the App wishlist section.
This being the Feature Requests section addressed at the developers of cloudron, All I wish for is a feature in cloudron that will provide additional/richer data and information about the performance of the apps, with alerts, charts, graphs, etc - New Relic provides this free of cost.
New Relic is one choice, they may be others too.
In other words, am seeking if we can have more information regarding the performance of our self-hosted server and the applications beyond the System Info (with disk usage, sys memory, cpu usage stats) and App Graphs (Memory), through integration with other third-party apps (preferably free).
I am just throwing this idea on to the feasibility/requirement wall, it may or may not stick.
