Jaeger简介

Jaeger：开源的端到端分布式跟踪，监视复杂的分布式系统中的事务并进行故障排除。
下图对比了常用的开源全链路追踪方案，目前SkyWalking和Pinpoint使用比较多，Jaeger相比客户端支持语言比较多，特别是对C++的支持，所以这次选择测试下。
Jaeger分布式跟踪工具初探

Jaeger解决的问题

  • 分布式事务监控
  • 性能和延迟优化
  • 根本原因分析
  • 服务依赖性分析
  • 分布式上下文传播

Jaeger架构图

Jaeger分布式跟踪工具初探

Jaeger组件

  • Jaeger Agent，负责和客户端通信，把收集到的追踪信息上报个收集器 Jaeger Collector
  • Jaeger Colletor把收集到的数据存入数据库或者其它存储器
  • Jaeger Query 负责对追踪数据进行查询
  • Jaeger Ingester 是一个从Kafka主题读取并写入另一个存储后端（Cassandra、Elasticsearch）的服务
  • Jaeger UI负责用户交互

Jaeger端口统计

Agent
5775 UDP协议，接收兼容zipkin的协议数据
6831 UDP协议，接收兼容jaeger的兼容协议
6832 UDP协议，接收jaeger的二进制协议
5778 HTTP协议，数据量大不建议使用

Collector
14267 tcp agent发送jaeger.thrift格式数据
14250 tcp agent发送proto格式数据（背后gRPC)
14268 http 直接接受客户端数据
14269 http 健康检查

Query
16686 http jaeger的前端，放给用户的接口
16687 http 健康检查

Jaeger部署

1.创建命名空间

[root@VM-0-123-centos jaeger]# kubectl create namespace jaeger

2.部署Jaeger-Operator
Jaeger Operator：Jaeger Operator for Kubernetes简化了在Kubernetes上的部署和运行Jaeger。
Jaeger Operator是Kubernetes operator的实现。操作员是一种软件，可以减轻运行另一软件的操作复杂性。从技术上讲，操作员是打包，部署和管理Kubernetes应用程序的一种方法。
Jaeger Operator版本跟踪Jaeger组件（查询，收集器，代理）的一种版本。发行新版本的Jaeger组件时，将发行新版本的操作员，该操作员了解如何将先前版本的运行实例升级到新版本。

[root@VM-0-123-centos jaeger]# kubectl create -n jaeger -f https://raw.githubusercontent.com/jaegertracing/jaeger-operator/master/deploy/crds/jaegertracing.io_jaegers_crd.yaml 
[root@VM-0-123-centos jaeger]# kubectl create -n jaeger -f https://raw.githubusercontent.com/jaegertracing/jaeger-operator/master/deploy/service_account.yaml
[root@VM-0-123-centos jaeger]# kubectl create -n jaeger -f https://raw.githubusercontent.com/jaegertracing/jaeger-operator/master/deploy/role.yaml
[root@VM-0-123-centos jaeger]# kubectl create -n jaeger -f https://raw.githubusercontent.com/jaegertracing/jaeger-operator/master/deploy/role_binding.yaml
[root@VM-0-123-centos jaeger]# kubectl create -n jaeger -f https://raw.githubusercontent.com/jaegertracing/jaeger-operator/master/deploy/operator.yaml

查看状态

[root@VM-0-123-centos jaeger]# kubectl get all -n jaeger
NAME                                         READY   STATUS        RESTARTS   AGE
pod/jaeger-operator-6ff67bdd4b-4nffk         1/1     Running       0          14d
pod/simple-prod-collector-59fc47bf5c-h26mq   0/1     Terminating   0          9d

NAME                              TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)             AGE

deployment.apps/jaeger-operator   1/1     1            1           14d

NAME                                         DESIRED   CURRENT   READY   AGE
replicaset.apps/jaeger-operator-6ff67bdd4b   1         1         1       14d

3.创建jaeger实例
创建jaeger.yaml文件，配置ES集群及限制Deployment/simple-prod-collector容器的cpu和内存使用大小。最大数量可以起10个pod。

apiVersion: jaegertracing.io/v1
kind: Jaeger
metadata:
  name: simple-prod
spec:
  strategy: production
  storage:
    type: elasticsearch
    options:
      es:
        server-urls: http://10.0.16.3:9200
        index-prefix: zhjt
  collector:
    maxReplicas: 10
    resources:
      limits:
        cpu: 500m
        memory: 512Mi
[root@VM-0-123-centos jaeger]# kubectl apply -f  jaeger.yaml  -n jaeger
jaeger.jaegertracing.io/simple-prod created

列出jaeger对象
备注：貌似使用官网all in one的例子状态是正常的Running，这里状态虽然是Failed，但是不影响使用。

[root@VM-0-123-centos jaeger]# kubectl get jaegers -n jaeger
NAME          STATUS   VERSION   STRATEGY     STORAGE         AGE
simple-prod   Failed   1.22.0    production   elasticsearch   9d

获取pod名字

[root@VM-0-123-centos jaeger]# kubectl get pods -l app.kubernetes.io/instance=simple-prod -n jaeger
NAME                                              READY   STATUS      RESTARTS   AGE
simple-prod-collector-59fc47bf5c-h26mq            1/1     Running     0          9d
simple-prod-query-85689b7bbd-g5jw9                2/2     Running     0          9d

获取pod日志

[root@VM-0-123-centos jaeger]# kubectl  logs simple-prod-query-85689b7bbd-g5jw9 jaeger-agent  -n jaeger

4.查看jaeger资源

如果流量大需要减小es压力，可以接入kafka集群，修改jaeger.yaml文件

apiVersion: jaegertracing.io/v1
kind: Jaeger
metadata:
  name: simple-streaming
spec:
  strategy: streaming
  collector:
    options:
      kafka:
        producer:
          topic: jaeger-spans
          brokers: my-cluster-kafka-brokers.kafka:9092   #修改为kafka地址
  ingester:
    options:
      kafka:
        consumer:
          topic: jaeger-spans
          brokers: my-cluster-kafka-brokers.kafka:9092  #修改为kafka地址
      ingester:
        deadlockInterval: 5s
  storage:
    type: elasticsearch
    options:
      es:
        server-urls: http://elasticsearch:9200   #修改为ES地址

5.agent部署

jaeger client的一个代理程序，client将收集到的调用链数据发给agent，然后由agent发给collector。由于使用的udp协议，一般部署在靠近client的位置。

agent有多种安装方式

1).docker安装

下载：jaegertracing/jaeger-agent Tags (docker.com)

docker run -d -p 6831:6831/udp -p 6832:6832/udp -p 5778:5778/tcp jaegertracing/jaeger-agent:1.12 --reporter.grpc.host-port=xx.xx.xx.xx:14250

2).k8s安装又分两种

sidecar方式

daemonset方式

参考：Operator for Kubernetes — Jaeger documentation (jaegertracing.io)

3).二进制安装

下载：Jaeger – Download Jaeger (jaegertracing.io)

nohup ./jaeger-agent --collector.host-port=xxxx:14267 1>1.log 2>2.log &

调研机构估计30%的智能手机可能受到高通芯片新漏洞的影响

根据调研机构的估计，全球约有三分之一的智能手机将会受到高通公司的调制解调器组件中一个新漏洞的影响。该漏洞可以使网络攻击者访问人们的手机通话和短信历史记录，甚至可以了解通话内容。 该漏洞(名称为CVE-2020-11292)位于高通移动站调制解调器(MSM)芯片中，该芯片允许手机设备连接到移动网络。 该芯片最初于上世纪90年代初设计，多年来不断进行更新以支持2G、3G、4G以及5G通信，并已逐渐成为世界上最普及的通信技术之一，尤其是在智能手机厂商中。 目前使用MSM芯片的设备包括谷歌、三星、LG、小米和One Plus销售的多种高端智能手机型号。 漏洞对高通MSM接口协议的影响 以色列安全服务商Check Point公司在日前发布的一份调查报告中声称，该公司研究人员在高通MSM接口(QMI)中发现了一个漏洞，该协议允许芯片与智能手机的操作系统进行通信。 调查表明，MSM组件通过QMI接口接收到格式错误的类型长度值(TLV)数据包，这可能会触发内存损坏(缓冲区溢出)，使网络攻击者可以运行他们自己的代码。 Check Point研究人员解释说：“在调查过程中，我们发现调制解调器数据服务中存在...

什么是线程安全？一文带你深入理解

前言 欢迎来到操作系统系列，采用图解 + 大白话的形式来讲解，让小白也能看懂，帮助大家快速科普入门。 上篇文章有介绍过进程与线程的基础知识，进程下拥有多个线程，虽然多线程间通信十分方便（同进程），但是却带来了线程安全问题，本篇主要就是介绍操作系统中是用什么方法解决多线程安全，废话不多说，进入正文吧。 博主希望读者阅读文章后可以养成思考与总结的习惯，只有这样才能把知识消化成自己的东西，而不是单纯的去记忆 内容大纲 小故事 带薪蹲坑，相信都是大伙都爱做的事情，阿星也不例外，但是我司所在的楼层的坑位较少，粥少僧多，十分烦恼。 阿星（线程A）每次去厕所（共享资源），门都是锁着的，说明有同事在里面占着坑（线程B持有锁），只能无奈的在外面乖乖的等着，不久后冲水声响起，同事爽完出来（线程B释放锁），阿星一个健步进入厕所把门锁住（线程A持有锁），享受属于自己的空间，晚来的其他同事只能乖乖排队，一切都是那么井然有序。 假设门锁坏了，井然有序就不存在了，上厕所不再是享受，而是高度紧张，防止门突然被打开，更糟糕的是，开门时，是个妹子，这下不仅仅是线程安全问题，还有数组越界了。 故事说完，扯了那么多，就是想说...
