I'm running yet another cloudwatch exporter, and /metrics is giving me a
200 response code with content-length 0. It's just fully empty.
# curl -vvv localhost:5000/metrics

There are no errors in the logs.

It responds to a request for "/" as expected, with "Thanks for using YACE
:)"
I would expect to at least see metadata about itself.
