Hi Anton I am interested in one-one mentorship. What should I do for the same

[@danielwojnar3876]

Great content! One of the best channels to learn from.

[@AntonPutra]

❤️

[@alkklajslkdajlk]

this is a best for studying trace basic with tempo and opentelemetry

[@AntonPutra]

thanks!

[@TrầnThếChinh-i9c]

Great content! very useful. Thank you very much!

[@thanhkhiet5089]

oh very detail explanation and useful, thank a lot!!!

[@AntonPutra]

Thank you, Thanh!

[@agun21st]

Very helpful video about tracing. I will implement on my project. Please make video on nodejs microservices Tracing with Opentelemetry and Tempo on AWS EKS.

[@AntonPutra]

Thanks noted! I’ll definitely create one about distributed tracing

[@YordisPrieto]

I wish you showed case using helm to add the tempo data source using terraform as well

[@AntonPutra]

I have an example but in different video - github.com/antonputra/tutorials/blob/8d7dd79f9c3c99eaa1f0af72e1936152634932a3/lessons/141/grafana/datasources.yaml#L4

Well done what about make video about Grafana-agent? It's a very promising thing and can replace all exporters in the cluste.

[@AntonPutra]

Thanks! Well, they push Grafana Cloud very hard. I wouldn't be surprised if, in the future, they leave it as the only option or introduce some kind of constraints that make it less usable for enterprises. By the way, they recently changed Grafana's license, which already has an effect. So be careful with them :)

Do you know anything about frontend tracing? Do you know of any implementation with Angular or React?

[@AntonPutra]

I'm very familiar with react, i may create something in the future

[@arozendojr]

@@AntonPutra I found Sentry, very good, frontend trancing and also runs on docker on primeses

[@AntonPutra]

@@arozendojr Ok I'll take a look. In prod we usually compile frontend to static files (httpml, js, css) and run it on CDN, but I guess you can ajax requests to public events.

Is it normal to have to manually place Jaeger Tracing in the application to be able to place the body inside Jaeger Web or is there an automatic way to see the body on a Tracing platform like Jaeger Web?

[@AntonPutra]

Some SDKs provide this functionality out of the box; for example, Java - as detailed at [opentelemetry.io/docs/instrumentation/java/manual/#automatic-configuration]. However, you still need to modify the source code. If you only want to trace calls between different microservices, it can be done at the infrastructure level.

How can I export metrics to prometheus ? metrics like count / histogram maybe

[@AntonPutra]

of course you can

[@bhanusudheer493]

it doesn't need otel operator to be installed

[@quantforce]

По акценту сразу понял, что ты русскоговорящий)

[@AntonPutra]

yeap

[@arozendojr]

Jaeger UI not the localhost ?

[@AntonPutra]

Did I even use Jaeger in that example? As far as I remember, I used the OpenTelemetry SDK to send data to Tempo storage and queried it from Grafana. Everything was hosted in Kubernetes.
