The visibility of logs, error logs, and information logs inside the built-in monitoring needs work because developers, when they implement code or any kind of specific tools, need proper control over the system.

To improve EMQX, I think it should reduce costs, save time when sending messages, and improve reliability.

If you want to improve further, the SSL certificate and TLS certificate have overhead in serverless EMQX.

On EMQX improvement side, I saw certain frameworks such as NanoMQTT and others claiming to be much more performant than EMQX, so maybe the newer version of EMQX can look into those aspects for potential improvements, but I do not have insight on the latest version of EMQX to know whether it has already addressed this or not.

I think EMQX can be improved by providing a uniform UI and login feature that we can use in the dashboard.
