Support OTEL over HTTP for Access Logs

[arkodg]

          @zirain any plans on doing otel over http?

writing a grpc service just to get the access log looks like overkill to me...

In most of the cases, otel-collector is the best choice as a backend/transit.

Maybe I can try this working!

Do you mean I need to fork the collector, create custom backend, compile, build, deploy, etc.?

[zirain]

otel-collector support both http and grpc, see the configuration here, you can use it as intermediary agent send to other exporters(e.g. another otel backend but http protocol).

Yeah. Ok. Thanks.

When I looked through the documentation, it seems that the configuration in OpenTelemetryAccessLogConfig.common_config does not support us to choose HTTP protocol for export. ref

You can extend it to support HTTP, just as OpenTelemetry tracer do.

您可以扩展它以支持 HTTP，就像 OpenTelemetry 跟踪器一样。

I started working on this and I don't quite understand it. Do we need to enhance and extend this in Envoy?

This seems to be a challenge for me, because I am not familiar with cpp and find it difficult to see this activity.
