In the
echo
server, it's possible to inject a custom Prometheus metrics registry. But if it was used, then metrics collected wasn't exposed in/metrics
since the Metric API didn't consider this custom metrics registry.This PR aims to fix that. But in the meantime it introduced a breaking change ... If someone has a better idea, I would be glad to hear it
