Distributed tracing does not capture grpc traffic and send spans

[abrekhov]

What is the issue?

I've installed linkerd, linkerd-jaeger with mutation webhook to send spans to grafana tempo, tempo itself, emojivoto (I also checked on googles online boutique microservices demo).

I see http spans but there is no grpc spans.

How can it be reproduced?

Install linkerd, linkerd-jaeger, tempo, test app with grpc. Try to generate the load.

Logs, error output, etc

No logs.

Hey @abrekhov! Sorry for the delay here. That error with the jaeger extension worries me, can you tell me how you installed this? I'd like to try it on my own.
