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 :-))

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.

There should be an update on this, Opentelementry has changed a lot

[@kernelguardian]

Just so if anyone runs into any "logLevel: LogLevel.ERROR TypeError: Cannot read property 'ERROR' of undefined" make sure you have the right package versions.

[@shrug_bug]

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

[@ritwizsinha1261]

Thank you this was the error I was facing

[@ds-pc9ys]

or use "DiagLogLevel" instead of "LogLevel"

[@bjo004]

Thanks for the very clear explanation. You covered metrics, traces but no logs. How can we open telemetry to instrument logs please?

[@otomazra7306]

I am here to LEARN

[@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.

opentelemetry is a giant PITA and way overcomplicated. It shouldnt be this complicated.

She missed the opportunity to show how the error was logged in the trace, for example when one service is up but another is not. I would have been a nice discussion.
