> Metrics endpoint could inform about supported request types, current response is
> {code}
> curl http://127.0.0.1:10090/metrics/vendor -X PUT
> No exporter found for method PUT and media type
> {code}
> OpenLiberty provide info which HTTP verbs are supported
> {code}
> curl https://localhost:9443/metrics/ --insecure -u theUser:thePassword -X PUT
> Error 405: CWMMC0001I: The method request type must be GET or OPTIONS.
> {code}
> Side comment - We return {{< HTTP/1.1 406 Not Acceptable}}, OpenLiberty returns {{< HTTP/1.1 405 Method Not Allowed}} which feels more appropriate.
> Spec speaks only about 404 and 406.
> {code}
> • 404 if a directly-addressed item does not exist. This may be a non-existing sub-tree or non- existing object
> • 406 if the HTTP Accept Header in the request cannot be handled by the server.
> {code}
> But 406 only mentions Accept Header, not the HTTP verb.
