The Looker+GA4 behavior is currently limiting. It also exposes the typical issue when relying on external “free” services. Are there ways I can bring my stats in-house?

2 aspects come to mind:

• Sending the event data…
• With the usual caveat of outage reliability, the data would be better hosted on my own server.
• An option would be to use MQTT to transport that data around.
• Viewing the data…
• Can I write my own Looker connector pulling data from my server?
• Are there other MQTT-based or similar web-based stats pages I can reuse?

I’m not particularly interested in writing my own graphs, even though I’ve certainly done that.

There are Linux packages that can pre-render graphs and I can expose them via ssl.

Can MQTT be used as either a transport mechanism, storage, or a data source?
