ActiveSupport notifications for Ruby on Rails

[danielmbarlow]

I looked for a specific Ruby repository to see if I should post this there, but didn't find one.

Is your feature request related to a problem? Please describe.

We need see how much time our Ruby on Rails application is taking on gRPC requests. In particular we're using the GoogleAds gem.

Describe the solution you'd like

I would like to be able to configure gRPC to provide ActiveSupport notifications like we get from the Excon HTTP library. Please see their documentation about that functionality. We found it very easy to use.

Describe alternatives you've considered

• I looked to see if InterceptorRegistry was available to callers, but it's internal to gRPC.
• I also checked our main interest in gRPC tracing: the GoogleAdsRuby gem. It implements interceptors. However it doesn't make the interceptor API public or provide ActiveSupport notifications

Same here, I am also interested in this.
@danielmbarlow Can you please tell me the solution you ended up with?

[danielmbarlow]

We wanted active support notifications because that would enable tracing in OpenCensus. In the end I don't think we really got a solution. However we are moving to OpenTelemetry. I haven't looked into it much, but there is an unfinished PR to implement gRpc instrumentation using OpenTelemetry:
