Learning Distributed Tracing 101

Distributing Tracing Lab

Learning Journey

Access the learning modules https://tracing.cloudnative101.dev

This learning journey will get you started into Distributed Tracing, covering many basic concepts with hands-on labs. The journey takes you through frameworks, client libraries, and Jaeger.

learning-distributed-tracing-101's Issues

Please remove anti-pattern of naming spans using URL

This looks like a useful tutorial for people getting started with tracing.

However, while browsing Node.js section (https://tracing.cloudnative101.dev/docs/lab-jaeger-nodejs.html) I noticed that the spans are given names like /sayHello/Carlos. This is a serious anti-pattern for most tracing systems. For explanation, please see the corresponding section in the OpenTelemetry (https://github.com/open-telemetry/opentelemetry-specification/blob/master/specification/trace/api.md#span), which is more up to date than OpenTracing spec.

Using git clone with ssh give errors in OpenLiberty Istio Lab

Using git clone with ssh give errors in OpenLiberty Istio Lab https://ibm-cloud-architecture.github.io/learning-distributed-tracing-101/docs/ocp-istio-ol.html

To reproduce

Instead of git clone with https the user might use ssh

git clone [email protected]:ibm-cloud-architecture/learning-distributed-tracing-101.git
cd learning-distributed-tracing-101

oc new-build . --strategy=docker --context-dir=lab-jaeger-istio-ol/service-a --name service-a-openliberty-istio

oc logs -f bc/service-a-openliberty-istio

Error:

Cloning "[email protected]:ibm-cloud-architecture/learning-distributed-tracing-101.git" ...
error: Host key verification failed.
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

We should add a note for the user, if they see this error on how to delete the buildconfig, and to use git clone with https and try again.

Not able to view traces in jaegerUI while running Open liberty project

Hi Team,

Good day.

I ran the docker-compose file in open liberty project which is in below path.
https://github.com/ibm-cloud-architecture/learning-distributed-tracing-101/tree/master/lab-jaeger-ol/solution

Traces are not appearing in jaeger UI path after hitting below end point couple of times
http://localhost:9080/sayHello/Carlos

I can able to view the increase of count in DAG tab. However Jaeger UI not showing any of the traces. I tried different search options.

Could you please assist on this ?

Add a Jaeger lab using OpenLiberty Microprofile

We have spring boot covered, but we are lacking a lab that shows how to instrument a microprofile java app with opentracing and jaeger

@nastacio is giving a talk and will be contributing this lab 🙌

tracing.cloudnative101.dev domain name is now defunct

From the README: Access the learning modules https://tracing.cloudnative101.dev/ which leads to an invalid domain

 Buy this domain
The owner of cloudnative101.dev is offering it for sale for an asking price of 69 USD!

Is there a replacement site? If not would it be OK to store the former content in a sub-directory in this repo?

rename lab menu items for java

Rename to

• Java Spring Boot
• Java Open Liberty

Unable to see application traces I see only istio traces

Please find attached traces showing only istio traces/spans and none from application. Please let me know if I am missing something.
