Does confighttp based HTTP server generate metrics like number of incoming requests?

[neelayu]

I am trying to explore if receivers built on top using confighttp.HTTPServerSettings generate useful metrics such as num of incoming requests, packets not forwarded to the processor(or exporter) etc. From the code I could see that the otelhttp instrumentation is used. However the /metrics endpoint on service.telemetry.metrics.address=:8888 endpoint reports no metrics(empty page) if we use telemetry.useOtelForInternalMetrics feature flag and basic obs views(exporter and processor metrics) otherwise.

Can anyone tell me if its the correct way to observe the collector?
Thanks

I know how it sounds, but the collector has limited self-observability capabilities. It should start changing once the Go SDK has the features we need. See #4198.
