這篇文章主要介紹了SpringBoot集成Zipkin實(shí)現(xiàn)分布式全鏈路監(jiān)控的方法啊，本文通過實(shí)例代碼給大家介紹的非常詳細(xì)，具有一定的參考借鑒價(jià)值,需要的朋友可以參考下

Zipkin 簡介

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.

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.

Zipkin是一種分布式跟蹤系統(tǒng)。它有助于收集解決服務(wù)體系結(jié)構(gòu)中的延遲問題所需的計(jì)時(shí)數(shù)據(jù)。功能包括收集和查找此數(shù)據(jù)。

Zipkin是Twitter基于google的分布式監(jiān)控系統(tǒng)Dapper（論文）的開發(fā)源實(shí)現(xiàn)，zipkin用于跟蹤分布式服務(wù)之間的應(yīng)用數(shù)據(jù)鏈路，分析處理延時(shí)，幫助我們改進(jìn)系統(tǒng)的性能和定位故障。Dapper論文地址

如果日志文件中有跟蹤ID，則可以直接跳轉(zhuǎn)到該文件。否則，你可以根據(jù)服務(wù)，操作名稱，tag標(biāo)簽和持續(xù)時(shí)間等屬性進(jìn)行查詢。將為您總結(jié)一些有趣的數(shù)據(jù)，例如在服務(wù)中花費(fèi)的時(shí)間占比，以及操作是否失敗。

應(yīng)用程序需要“檢測”以向Zipkin報(bào)告跟蹤數(shù)據(jù)。這通常意味著配置跟蹤器或檢測庫。向Zipkin報(bào)告數(shù)據(jù)的最常用方法是通過http或Kafka，盡管存在許多其他選項(xiàng)，例如Apache ActiveMQ，gRPC和RabbitMQ。提供給UI的數(shù)據(jù)存儲(chǔ)在內(nèi)存中，或者持久存儲(chǔ)在受支持的后端（如Apache Cassandra或Elasticsearch）中。

本示例中是使用Zipkin中集成的http組件進(jìn)行發(fā)送Span數(shù)據(jù)。

Springboot 集成 Zipkin

安裝啟動(dòng) zipkin

https://github.com/openzipkin/zipkin 中下載 zipkin.jar

java -jar zipkin.jar

版本說明

框架組件	Version
springboot	2.1.6.RELEASE
zipkin	3.9.0

項(xiàng)目結(jié)構(gòu)

項(xiàng)目采用父工程集成多模塊的方式構(gòu)建而成，demo-zipkin 父工程聚合了zipkin-1、zipkin-2、zipkin-3、zipkin-4、zipkin-5 五個(gè) Module。

demo-zipkin
 zipkin-1
 |-SpanCollectorConfig
 |-application.properties
 |-ZipkinController
 |-Application1
 zipkin-2
 |-SpanCollectorConfig
 |-application.properties
 |-ZipkinController2
 |-Application1
 zipkin-3
 |-SpanCollectorConfig
 |-application.properties
 |-ZipkinController3
 |-Application1
 zipkin-4
 |-SpanCollectorConfig
 |-application.properties
 |-ZipkinController4
 |-Application1
 zipkin-5
 |-SpanCollectorConfig
 |-application.properties
 |-ZipkinController5
 |-Application1

工程端口分配

每個(gè) Module 使用不同的端口，分別啟動(dòng)自己的Application。

Module名稱	端口	Application
zipkin-1	8081	Application1
zipkin-2	8082	Application2
zipkin-3	8083	Application3
zipkin-4	8084	Application4
zipkin-5	8085	Application5

引入 Maven 依賴

配置文件、收集器的設(shè)置

配置 application.properties，以 zipkin-1 為例，其他工程中配置時(shí)將 zipkin.serviceName與server.port更改為 myzipkin-2 …與8081...等即可

zipkin.serviceName=myzipkin-1
zipkin.url=http://localhost:9411
zipkin.connectTimeout=6000
zipkin.readTimeout=6000
zipkin.flushInterval=1
zipkin.compressionEnabled=true
zipkin.samplerRate=1

server.port=8081
server.servlet.context-path=/

配置Span收集器

設(shè)置收集器的詳細(xì)參數(shù)，包含超時(shí)時(shí)間、上傳span間隔、以及配置采集率等，進(jìn)而對收集器進(jìn)行初始化。

運(yùn)行分析

在地址欄請求urlhttp://localhost:8081/zipkin/service1，然后訪問http://localhost:9411/zipkin/

查看服務(wù)調(diào)用耗時(shí)

查看服務(wù)依賴關(guān)系

核心概念

通過上圖可以了解到共有7個(gè)span，分別為

{
 "zipkin-1":["Server Start", "Server Finish"]，
 "myzipkin-1,myzipkin-2":
 ["Client Start", "Server Start", "Client Finish", "Server Finish"],
 "myzipkin-2,myzipkin-3":
  ["Client Start", "Server Start", "Client Finish", "Server Finish"],
 "myzipkin-3,myzipkin-4":
  ["Client Start", "Server Start", "Client Finish", "Server Finish"],
 "myzipkin-4,myzipkin-5":
  ["Client Start", "Server Start", "Client Finish", "Server Finish"],
 "myzipkin-2,myzipkin-4":
  ["Client Start", "Server Start", "Client Finish", "Server Finish"],
 "myzipkin-4,myzipkin-5":
  ["Client Start", "Server Start", "Client Finish", "Server Finish"],
}

在json文件中選取兩個(gè)子集進(jìn)行分析

基本數(shù)據(jù)：用于跟蹤樹中節(jié)點(diǎn)的關(guān)聯(lián)和界面展示，包括traceId、spanId、parentId、name、timestamp和duration，其中parentId為null的Span將成為跟蹤樹的根節(jié)點(diǎn)來展示，當(dāng)然它也是調(diào)用鏈的起點(diǎn)，為了節(jié)省一次spanId的創(chuàng)建開銷，讓頂級Span變得更明顯，頂級Span中spanId將會(huì)和traceId相同。timestamp用于記錄調(diào)用的起始時(shí)間，而duration表示此次調(diào)用的總耗時(shí)，所以timestamp+duration將表示成調(diào)用的結(jié)束時(shí)間，而duration在跟蹤樹中將表示成該Span的時(shí)間條的長度。需要注意的是，這里的name用于在跟蹤樹節(jié)點(diǎn)的時(shí)間條上展示。traceId：標(biāo)記一次請求的跟蹤，相關(guān)的Spans都有相同的traceId。kind ：zipkin最新V2版本的API中，不再要求在annotations中上傳cs,cr,sr,ss。而是通過kind標(biāo)記是server-side span還是client-side span，兩端記錄自己的timestap來取代cs和sr，記錄duration來取代cr和ss

{
 "traceId": "867a9e3867736b17",
 "parentId": "96f19423db38c90d",
 "id": "6c9fd521b6589b7f",
