[jboss-jira] [JBoss JIRA] (WFWIP-152) Metrics endpoint should inform about supported request types, HTTP code change to be considered

[Jeff Mesnil (Jira)]

     [ https://issues.jboss.org/browse/WFWIP-152?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jeff Mesnil resolved WFWIP-152.
-------------------------------
    Resolution: Deferred


This type of enhancement should be done at the MP Metrics level (or at least in SmallRye implementation) which is where the HTTP endpoints are specified.

Once they are specified, we can then support them in WildFly.

> 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.
