Elixir GRPC instrumentation

[diegogl12]

I'm currently using the elixir grpc lib and noticed that there is no support for this lib in the OTEL world.
Currently, here we can find the grpcbox support, but in my understanding, it's a different lib and approach from the elixir grpc.

I was exploring the GRPC.ServerInterceptor and GRPC.ClientInterceptor that could be useful ways to handle this OTEL collection.

I was also inspired by the Prometheus support for the elixir gRPC.

I was energized to implement new instrumentation to have this support. Any thoughts?

A library for Elixir grpc would be great! And right, grpcbox is unrelated to elixir-grpc. It just happens to be the one I use (and OpenTelemetry exporter uses) so I wrote the instrumentation library for it.

Awesome... I'll start to look into it! 😊

Would this deal with this? I ran into this last year and have had no time to deal with it.

I don't think so. You had an issue related to ecto (if I understood). Here I'm proposing new instrumentation for the lib.

Maybe confusion around RPC/GRPC?

Yep, The g never registered. Apologies.
