Very interesting, thanks! Just one thing. For next time, when you make a video, can you explicitly add the version numbers? Whereas it would have worked fine 4 months ago, there have been breaking changes now. (I'm glad you added a link to the source code, where I could find the dependency discrepancies :-))

Hi. Thank you very much for the video. Also I have a question. I have a react front end. Is that application can configure same as this? or is it a problem when we build and deploy it. Thank you very much..

[@kumarabhishek7877]

Great Course

[@shilongjaycui-tech]

Great tutorial. Unfortunately things broke for me around 30:23 probably because the version of JavaScript used in the tutorial is outdated at my time of viewing... but that's okay. I'm going to resume my OpenTelemetry learning at the official website. Still, thank you for the tutorial Ania! Edit: But for those of you who keep going in the course, here're the Makefile targets I came up with while following the tutorial. Hopefully they'll save you some manual work: run-zipkin: # Set up Zipkin, a tracing backend to which I can export traces. docker run --rm -d -p 9411:9411 --name zipkin openzipkin/zipkin stop-zipkin: # Tear down Zipkin. docker stop zipkin package-json: # Turn the folder into an npm package. echo "Hit 'enter' for all the subsequent prompts." npm init install: npm i @opentelemetry/core \ @opentelemetry/node \ @opentelemetry/plugin-http \ @opentelemetry/plugin-https \ @opentelemetry/exporter-zipkin \ @opentelemetry/tracing \ express \ @opentelemetry/plugin-express \ run-app-with-tracing: # tracing initialization happens before application code runs node -r ./tracing.js app.js

Incase you are having permission pulling zipkin from docker please know that "openzipkin/zipkin" is correct, i think the way it seem on this tutorial it was like "open zipkin/zipkin". If you met this error you would know what i mean.

[@gbisaga]

In the example, tracing.js does not work, it gets an error on line 9, "Cannot read property `ERROR` of undefined." The problem seems to be that @opentelemetry/core does not export LogLevel. When I comment out LogLevel it runs, but it does not send any telemetry. I verified this by using ConsoleSpanExporter.

[@gbisaga]

If anybody gets the same error, they broke backward compatibility in the newer minor version 0.19.0. Use the exact versions (0.16.0) shown in the package.json and it will work.

[@gbisaga]

And... the Prometheus code as shown doesn't exist in the opentelemetry page either. I appreciate this course, still useful to listen to, but bottom line is that this code seems extremely unstable and trying to follow through a tutorial like this is very frustrating.

[@aniakubow]

@@gbisaga all the code repos can be pulled from my personal repo 🙂 (in the video description ) if you pull the project will have the correct versions. Opentelemetry is really new and hence evolving at a fast rate.

[@gbisaga]

@@aniakubow Thanks, that's what I ended up doing. But I have to say, I have a concern that code I might write today will be obsoleted soon. I really like the idea of OpenTelemetry, but how can I recommend it if I can't trust the API not to change in a couple of months? Plus, the documentation on their site is still giving the old version.

[@readdir]

Try reading the documentation instead of complaining and blaming the video. Many people who haven't even watched this video have gotten OpenTelemetry to work. And trust me, OpenTelemetry is here to stay. It's not some shitty unsupported library. Go read about its status on the CNCF.

Can you be a bit more specific? I have "@opentelemetry/core": "^0.21.0". What package and versions should I check?

[@kernelguardian]

@@shrug_bug Ideally you should install packages mentioned in this package.json file github.com/kubowania/opentelemetry-tracing/blob/main/package.json

[@shrug_bug]

Thanks! For anyone running into this error, the following worked for me. Copy/paste the dependancies from the above package.json file into your package.json file, then run "npm i" in terminal. This will re-install the EXACT versions that are needed
