OpenTelemetry Support

[kshcherban]

Please advise do you plan to migrate from OpenCensus to OpenTelemetry?
I've seen some discussion around it in #109 but there's no track of any progress.

cc @simonz130 do you know of any progress?

We hope to migrate this app from OpenCensus to OpenTelemetry in the April-May 2021 timeframe, thanks for your patience.

Update: after discussing with our team, we have decided to keep the upstream OnlineBoutique as a reference for OpenCensus, until its eventual deprecation.

The Cloud Ops Sandbox provides an OnlineBoutique + OpenTelemetry reference. You are also welcome to fork this repo and replace OpenCensus with OpenTelemetry.

Checking in on this issue, do you expect to update to Otel still? Thanks.

Hello all,
if someone else comes across this ticket, I've forked and instrumented the Online Boutique with OpenTelemetry:
https://github.com/julianocosta89/opentelemetry-microservices-demo

I've added an OpenTelemetry Collector and Jaeger to it as well.

I've also removed the OpenCensus and Cloud Operations (Stackdriver).
All the changes are documented in this PR:
julianocosta89#1

We did the same, here is the fork with lots of Otel added. https://github.com/logzio/microservices-demo

Just adding this new CNCF blog article for reference too: https://www.cncf.io/blog/2022/04/04/learn-opentelemetry-tracing-with-this-lightweight-microservices-demo/.

Bumping this to p3, but we should consider making the switch (cc: @NimJay)

[mathieu-benoit]

Is it something you could implement during one of your rotation @arbrown or @minherz?

[julianocosta89]

@mathieu-benoit the Otel community is working on a demo that was based on the hipster shop: https://github.com/open-telemetry/opentelemetry-demo

[mathieu-benoit]

Wow, thanks @julianocosta89, the idea was already to leverage the content you previously shared with us: #422 (comment). We will now make sure that we are leveraging the latest and greatest from https://github.com/open-telemetry/opentelemetry-demo. Thanks for sharing, much appreciated!

As an update:

As of #1180, we have a kustomize module for deploying the OpenTelemetry Collector and turning on distributed tracing in the microservices. Expect basic support for custom metrics and managed Prometheus this year.
