How do I show the count of a specific group of metrics from a prometheus histogram?

So, I have a histogram that collects duration in seconds for some operations, metrics are:

And this works, I get my quantiles and all, but I want to get a count of all requests that go over 1 second. How do I produce a query like that?

rate(rpc_request_duration_seconds_bucket{le="+Inf"}[1m]) 
  - ignoring(le)
rate(rpc_request_duration_seconds_bucket{le="1.0"}[1m])

will return how many queries are going over 1s every second.

This is all queries, minus the queries that take less than or equal to one second.

You want to write something like

rate(rpc_request_duration_seconds_count [1m])

This will give you the requests per second in a (sliding) interval of 1 minute. See the Query functions doc of Prometheus.
