Prometheus New Registry enable HTTP Metrics

I am using:

var registry = prometheus.NewRegistry() 

I know I can do for some goroutine (etc.) related metrics:

registry.MustRegistry(collectors.NewGoCollector()); 

But, I cannot see http metrics which I see when using default registry, like:

promhttp_metric_handler_requests_total{code="200"} 1 promhttp_metric_handler_requests_total{code="500"} 0 promhttp_metric_handler_requests_total{code="503"} 0 

How to bring these metrics?

Also, I cannot see http_requests_total irrespective of the registry I use. Is there a way to automatically expose it (instead of defining it)?

You also need to register your custom defined metric like http_requests_total (in this case).

This should solve your problem :

`registry.MustRegistry(promHttpRequestTotal)

Here promHttpRequestTotal is the variable in which your metric http_requests_total is defined.
