kandi X-RAY | zipkin Summary

zipkin is a Java library typically used in Performance Management, Monitoring, Prometheus applications. zipkin has no bugs, it has no vulnerabilities, it has build file available, it has a Permissive License and it has high support. You can download it from GitHub, Maven.

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

OCI APM domain with Istio zipkin not pushing tracing details

Asked 2022-Apr-05 at 12:46

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.

                    }
                }
            }]
        }
    }

above configmap not working as expected, the sidecar is crashing due to missing key connection_timeout although after adding in configmap sidecar not showing error.

There is no error found in Zipkin or Istiod containers, not sure how to debug further.

After 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

Opentelemetry set up for Angular Project- Export to Zipkin Problem

Asked 2022-Mar-31 at 21:37

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.

This is what I've done on this project:

Environment.ts file:

import { DiagLogLevel } from '@opentelemetry/api';
import {
  OpenTelemetryConfig
} from '@jufab/opentelemetry-angular-interceptor';

interface IEnvironment {
  production: boolean;
  urlTest: string;
  openTelemetryConfig: OpenTelemetryConfig;
}

// Example to configure the angular-interceptor library
export const environment: IEnvironment = {
  production: false,
  urlTest: 'http://localhost:4200',
  openTelemetryConfig: {
    commonConfig: {
      console: true, // Display trace on console
      production: true, // Send Trace with BatchSpanProcessor (true) or SimpleSpanProcessor (false)
      serviceName: 'instrumentation-example', // Service name send in trace
      probabilitySampler: '1', // 75% sampling
      logLevel: DiagLogLevel.ALL //ALL Log, DiagLogLevel is an Enum from @opentelemetry/api
    },
    zipkinConfig: {
      url: 'http://localhost:9411/api/v2/spans'
    },
    b3PropagatorConfig: {
      multiHeader: '0' //Value : 'O' (single), '1' (multi)
    },
    instrumentationConfig: {
      xmlHttpRequest: true,
      fetch: true,
      documentLoad: true,
    }
  }
};

app.module.ts file:

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';

import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
import {
  ZipkinExporterModule,
  CompositePropagatorModule,
  OtelWebTracerModule,
} from '@jufab/opentelemetry-angular-interceptor';
import { environment } from '../environments/environment';

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    ZipkinExporterModule,
    BrowserModule,
    AppRoutingModule,
    //Insert propagator module
    CompositePropagatorModule,
    OtelWebTracerModule.forRoot(environment.openTelemetryConfig),
    
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

Added configuration to environment.ts file and imported all necessary modules including ZipkinExporterModule to app.module.ts but can't see the traces on Zipkin.

Opentelemetry- Typescript Project (Zipkin exporter)

Asked 2022-Mar-30 at 15:33

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

tracer.ts

import { NodeTracerProvider } from '@opentelemetry/sdk-trace-node';
import { SimpleSpanProcessor, BatchSpanProcessor, ConsoleSpanExporter, } from '@opentelemetry/sdk-trace-base';

}

const provider = new NodeTracerProvider({
    resource: new Resource({
        [SemanticResourceAttributes.SERVICE_NAME]: serviceName
    }),
});
    
//export to console
provider.addSpanProcessor(new SimpleSpanProcessor(new ConsoleSpanExporter()));

  });

  return opentelemetry.trace.getTracer(serviceName);
};

And the the way the tracer was being called as well:
app.ts

require('./tracer.ts')('app-services');

const express = require('express');

const app = express();

app.get('/', (req, res) =>{
    res.send('Hello');
});

app.listen(3200, () => console.log('Server running'));

I've tested locally and I can see traces in the Console and in Zipkin.

QUESTION

Building Docker image from spring maven project for arm64 platform

Asked 2022-Mar-24 at 00:10

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:

FROM --platform=linux/arm64 maven:3.8.4-jdk-11 AS build
COPY src /home/path_to_app/src
COPY pom.xml /home/path_to_app
RUN mvn -f /home/path_to_app/pom.xml spring-boot:build-image -DskipTests

My project structure is:

standard maven structure

In terminal, at same pom.xml directory I run: docker buildx build --platform linux/arm64 --tag <mytag> .

Logs successful until =>Building image 'docker.io/myusername/myimage:mytag', then an exception occurs and build fails.

My docker daemon is running. Can't figure out why it tries to reach localhost:2376 (There is no such port in my project). My DOCKER_HOST is set to unix:///var/run/docker.sock and works fine. Tried to add to daemon.json:

{
"hosts": ["tcp://127.0.0.1:2376", "unix:///var/run/docker.sock"]
}

but docker daemon can't initialize (binding error, port already in use)

I don't know where does com.sun.jna.LastErrorException come from.

I suspect that maybe Docker in docker (dind) is needed, but I don't know how to set it up in my Dockerfile. Or maybe a port binding configuration.

Thank in advance for any help!!!

Note: I just want to build the image locally. I don't wish pushing to docker registry. I don't want any other stages in the build process.

Answered 2022-Mar-24 at 00:10

Building 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.

Java Brave: .spanReporter() deprecated in Tracing.newBuilder().localServiceName("service").spanReporter(reporter).build();

Asked 2022-Feb-27 at 14:20

Small question regarding Java Brave please.

I have a very small piece of code:

OkHttpSender        sender   = OkHttpSender.newBuilder().endpoint("https://zipkin-instance.com:9411/api/v2/spans").build();
AsyncReporter<Span> reporter = AsyncReporter.builder(sender).build();
Tracing             tracing  = Tracing.newBuilder().localServiceName("service").spanReporter(reporter).build();

The code is working fine, but after a version bump:

 <dependency>

            <version>2.16.3</version>
        </dependency>

I am seeing this being deprecated: .spanReporter(reporter)

Looking at the documentation, I am not able to see what is this deprecated in favor of.

May I ask what is the new equivalent of this please?

OkHttpSender        sender   = OkHttpSender.newBuilder().endpoint("https://zipkin-instance.com:9411/api/v2/spans").build();
AsyncReporter<Span> reporter = AsyncReporter.builder(sender).build();
Tracing             tracing  = Tracing.newBuilder().localServiceName("service").spanReporter(reporter).build();

Thank you

If 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:

 // Configure a reporter, which controls how often spans are sent
 //   (this dependency is io.zipkin.reporter2:zipkin-sender-okhttp3)
 sender = OkHttpSender.create("http://127.0.0.1:9411/api/v2/spans");
 //   (this dependency is io.zipkin.reporter2:zipkin-reporter-brave)
 zipkinSpanHandler = AsyncZipkinSpanHandler.create(sender); // don't forget to close!

 // Create a tracing component with the service name you want to see in Zipkin.
 tracing = Tracing.newBuilder()
                  .localServiceName("my-service")
                  .addSpanHandler(zipkinSpanHandler)
                  .build();
