> Those are entirely different orders of magnitude both when it comes to size and how much usefulness you lose. In modern storage backends like Victoriametrics a counter gonna cost you around byte per metric per probe. And as you emit them periodically, that is essentially independent of incoming traffic

I thought this argument was about whether wide events can be used for metrics or metrics is a completely different concept. If we want to emulate metrics in events, we would also make them periodically independently of the traffic. Like emit them once in a while. Pretty much like Prometheus scraping works
