## Exporting metrics with handlers
Cowboy 1:
```erlang
Routes = [
{'_', [
{"/metrics/[:registry]", prometheus_cowboy1_handler, []},
{"/", toppage_handler, []}
]}
]
```
Cowboy 2:
```erlang
Routes = [
{'_', [
{"/metrics/[:registry]", prometheus_cowboy2_handler, []},
{"/", toppage_handler, []}
]}
]
```
## Exporting Cowboy2 metrics
```erlang
{ok, _} = cowboy:start_clear(http, [{port, 0}],
#{env => #{dispatch => Dispatch},
metrics_callback => fun prometheus_cowboy2_instrumenter:observe/1,
stream_handlers => [cowboy_metrics_h, cowboy_stream_h]})
```
