The name of the type

Using the default labels, registers the following metrics:

• request_active{path, method} (up-down-counter)
• request_total{path, method, status} (counter)
• request_duration{path, method, status, phase} (histogram)

Status is by default the status code class (1xx, 2xx, etc.), and phase can be either headers or body - request duration is measured separately up to the point where the headers are determined, and then once again when the whole response body is complete.

Registers default metrics (see other variants) using custom labels.
