kandi X-RAY | zipkin Summary
Zipkin is a distributed tracing system. It helps gather timing data needed to troubleshoot latency problems in service architectures. Features include both the collection and lookup of this data. If you have a trace ID in a log file, you can jump directly to it. Otherwise, you can query based on attributes such as service, operation name, tags and duration. Some interesting data will be summarized for you, such as the percentage of time spent in a service, and whether or not operations failed. The Zipkin UI also presents a dependency diagram showing how many traced requests went through each application. This can be helpful for identifying aggregate behavior including error paths or calls to deprecated services. Application’s need to be “instrumented” to report trace data to Zipkin. This usually means configuration of a tracer or instrumentation library. The most popular ways to report data to Zipkin are via http or Kafka, though many other options exist, such as Apache ActiveMQ, gRPC and RabbitMQ. The data served to the UI is stored in-memory, or persistently with a supported backend such as Apache Cassandra or Elasticsearch.

QUESTION
i am following this document to set up the distributed tracing : https://docs.oracle.com/en-us/iaas/Content/ContEng/Tasks/contengistio-intro-topic.htm#exploring_istio_observability
My Cluster is on GKE GCP for testing purposes, installed istio top of it and followed document and setup services.
Services are up and running with Prometheus, Grafana, Jeger & Zipkin.
It's failing from step : Performing Distributed Tracing with OCI Application Performance Monitoring.
Tried udpating configmap for sidecar injector so that i can push tracing details to zipkin domain.
Configured Zipkin domain and using public-span use of now in configmap.
ANSWER
Answered 2022-Apr-05 at 12:46After 2-3 days of debugging was able to resolve distributed tracing issue with istio, Zipkin and OCI APM.
Note : With root user it was not working, so I created one compartment in OCI created IAM policy, group and give full access of compartment to the group.
Added root user to group and weirdly it started working while with direct root user and default policy it was not working.
Ref doc for policy : https://docs-uat.us.oracle.com/en/cloud/paas/application-performance-monitoring/apmgn/perform-oracle-cloud-infrastructure-prerequisite-tasks.html
Working configmap sidecar
connect_timeout key is required otherwise sidecar is failing and due to that PODs won't come in Ready state. Port 443 mentioned in the official documentation is not required.

I have a hello-world Angular project that I'm trying to set up opentelemetry on it. There is no back end and I just want to see the traces for the frontend. I followed the instruction provided by the following library but I don't get the traces on Zipkin: opentelemetry-angular-interceptor
There is no specific error when I run ng serve, I just can't see the traces.

I have a simple hello-world typescript project that I'm trying to set up opentelemetry on it. I want to send the traces to console and Zipkin.
I run the app but I don't get any tracer neither on console nor on Zipkin. I can't exactly pin-point what's the problem as I exported the init function (set up tracer in this function) and imported it in the app.ts file but for some reasons I can't get the tracers. There is no error when I run the app.
This is a simple project with two files: tracer.ts and app.ts

QUESTION
I'm in a Spring course, and I have a maven application (downloaded from the course resources) built from spring initializr. I can build a local Docker image with mvn spring-boot:build-image (no Dockerfile in the project). By default a Docker image is built as linux/amd64, but I am working with a M1 Apple Silicon chip (arm64). I've been looking many workarounds but with no success. Lastly, I found that maybe adding a Dockerfile and specifying the platform it would build the image accordingly.
My goal is to build a docker image for arm64 architecture.
So, I created a Dockerfile:
...ANSWER
Answered 2022-Mar-24 at 00:10Building an ARM-based image is not currently possible with mvn spring-boot:build-image, because the Cloud Native Buildpacks builders that Spring Boot integrates with do not support this. This is one of the possible items of focus on the Paketo buildpacks 2022 roadmap, which you can cast votes for.
CNB documents a work-around for this, but it's not simple to set up and run.
RUN mvn -f /home/path_to_app/pom.xml spring-boot:build-image -DskipTests
You would need Docker-in-Docker to make something like this work, since the CNB builder processes that would run inside the Docker container need to talk to the Docker daemon. Regardless, this would not allow you to build an ARM image for the reasons stated above.

QUESTION
Small question regarding Java Brave please.
I have a very small piece of code:
...ANSWER
Answered 2022-Feb-27 at 14:20If you look at the JavaDoc of the method spanReporter in Tracing.builder (brave 5.13.7), you will have the answer:
Deprecated. Since 5.12, use addSpanHandler(SpanHandler) with a ZipkinSpanHandler
Since 5.12, this is deprecated for using ZipkinSpanHandler in the io.zipkin.reporter2:zipkin-reporter-brave library.
For example, here's how to batch send spans via HTTP to a Zipkin-compatible endpoint:
QUESTION
I'm setting up an application that uses Brave to perform tracing of processing spans. Configuring it to send traces is relatively straightforward, but what I want to do is make tracing optional - that is, most of the time, nobody wants or cares about the tracing data and zipkin isn't even running.
For those sorts of configurations, it seems like one option is to implement zipkin2.reporter.Sender with a null implementation, but that seems harder than it needs to be, and still a lot of the machinery keeps running for no reason.

QUESTION
I send my traces to Zipkin and I can tell I am setting the HTTP Path
But it does not map to XRay's Request URL.
Where can I do the mapping?
I am using the following images as per my answer on integrating Spring Cloud Sleuth with Amazon X-Ray
- amazon/aws-xray-daemon:latest
- ghcr.io/openzipkin/zipkin-aws:latest
Looking through the code, I am using HttpTracing from ZipKin brave libraries I am presuming that's what it is using to populate the data.
Digging around some more there seems to be an openzipkin/zipkin-aws#58 which sort of describes the issue
...ANSWER
Answered 2022-Feb-18 at 19:56Looking through the code I may just need to alter the default tracing to add the additional details. Adding the following bean will make it configure to contain the necessary details.
