How to config metrics properly ?

Hey @dfang,

Thanks for flagging the issue. Mind sharing what your setup looks like?

I'm running

1. make dev
2. make db_start
3. curl -X 'GET' 'http://localhost:4000/metrics' -H 'accept: application/json' -H 'Content-Type: application/json' -H 'Authorization: Bearer eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJpYXQiOjE2ODAxNjIxNTR9.U9orU6YYqXAtpF8uAiw6MS553tm4XxRzxOhz2IwDhpY' | jq

and am able to receive metrics.

Here's a truncated sample:

# HELP supavisor_prom_ex_phoenix_endpoint_port_info The configured port of the Endpoint module.
# TYPE supavisor_prom_ex_phoenix_endpoint_port_info gauge
supavisor_prom_ex_phoenix_endpoint_port_info{endpoint="SupavisorWeb.Endpoint",port="4000",host="127.0.0.1",region="eu",short_alloc_id="111e4567"} 1
# HELP supavisor_prom_ex_phoenix_endpoint_url_info The configured URL of the Endpoint module.
# TYPE supavisor_prom_ex_phoenix_endpoint_url_info gauge
supavisor_prom_ex_phoenix_endpoint_url_info{endpoint="SupavisorWeb.Endpoint",url="http://localhost:4000",host="127.0.0.1",region="eu",short_alloc_id="111e4567"} 1
# HELP supavisor_prom_ex_beam_system_schedulers_online_info The number of scheduler threads that are online.
# TYPE supavisor_prom_ex_beam_system_schedulers_online_info gauge
supavisor_prom_ex_beam_system_schedulers_online_info{host="127.0.0.1",region="eu",short_alloc_id="111e4567"} 10
# HELP supavisor_prom_ex_beam_system_schedulers_info The number of scheduler threads in use by the BEAM.
# TYPE supavisor_prom_ex_beam_system_schedulers_info gauge
supavisor_prom_ex_beam_system_schedulers_info{host="127.0.0.1",region="eu",short_alloc_id="111e4567"} 10
# HELP supavisor_prom_ex_beam_system_dirty_io_schedulers_info The total number of dirty I/O schedulers used to execute I/O bound native functions.
# TYPE supavisor_prom_ex_beam_system_dirty_io_schedulers_info gauge
