[Question]Why there's no xx.total metrics in semantic-conventions

[caibirdme]

I've learned the semantic-conventions, and found that no matter http.server.xxx or rpc.server.xxx, there's no metrics for counting the request total. I'm curious about the reason. Like we have http.server.request.duration histogram and http.server.active_requests updowncounter, but don't have http.server.request.total count, why is that? Most people care about the qps which requires the xx.total metrics, but we don't have that, I don't know if it's designed to be so, and why

hi @caibirdme! the total is available via the http.server.request.duration histogram, does this work for you?

Could you elaborate more please? How the histogram "http.server.request.duration" that measures request duration can be transformed into a counter metric? So that it can be calculated the number of requests per second (rps) for each http.target?

summing the counts across the histogram buckets will give you the total
