The same clarification would be needed if x-forwarded-host
exists but x-forwarded-proto
does not, and x-forwarded-host
does not contain port information.
I would recommend either option 1 or option 5.
my initial thought is option 1
IIRC the purpose of making the port required when address is present was just to avoid the "default value" problem (does missing port imply default or imply it just wasn't captured)
in this case, a missing port value really would mean that it just couldn't be collected for some reason

Is your change request related to a problem? Please describe.
In https://github.com/open-telemetry/semantic-conventions/blob/bf0a2c1134f206f034408b201dbec37960ed60ec/docs/http/http-spans.md#clientserver-example-with-reverse-proxy the forwarded header may not contain enough information to determine the port if it contains
host
but notproto
. The http semconv states that port is required if address exists.Describe the solution you'd like
Please clarify what to do in this situation:
x-forwarded-host
orhost
headers, or use port of proxied requestForwarded
headerDescribe alternatives you've considered
No response
Additional context
While the
Forwarded
should contain enough information to determine the port, it may not in every situation. In these types of unexpected situations, telemetry is more important than ever.
