http.response.status_code Activitiy not accessible on Processor?

[renatosc]

I created a custom Processor and add it as the last one before my ConsoleExporter. I see on my console that my request does have an Activity.Tag "http.response.status_code" but my Processor doesn't not see that tag, which means it is being defined after my Processor. But as I said, my Processor is the last one added. So, does that mean that I cannot access that Activity tag using a Processor? Are there any other alternatives to have access to that http.response.status_code tag?

Can you share a minimal repro? Also, make sure you are inspecting the Activity in the onend callback, not onstart in the processor.

@renatosc I re-checked this. I am able to repro it. Its odd. Will take a look. Do you mind opening an issue https://github.com/open-telemetry/opentelemetry-dotnet/issues

[vishweshbankwar]

never mind - You are looking at Tags. You should look at TagObjects
See

opentelemetry-dotnet/src/OpenTelemetry.Exporter.Console/ConsoleActivityExporter.cs

Line 45 in 42ecd73

foreach (ref readonly var tag in activity.EnumerateTagObjects())

Thank you. That was it. I read about TagObjects but I thought that it was only related to custom exporters.

https://github.com/open-telemetry/opentelemetry-dotnet/tree/main/docs/trace/extending-the-sdk#enriching-processor It'd be good to update these docs to call this out. A common mistake I guess to confuse between Tags and TagObjects, in the absence of docs.

[renatosc]

@cijothomas I submitted a PR to update the docs as you suggested. The Exporters section already have that this called out, but the Processors one didn't, so I added one there as well.

Thank you again for the help.
