1. skywalking

官網(wǎng):https://skywalking.apache.org/

特點(diǎn):

1.SkyWalking: 一個(gè)開源的可觀測(cè)平臺(tái), 用于從服務(wù)和云原生基礎(chǔ)設(shè)施收集, 分析, 聚合及可視化數(shù)據(jù)。
2.SkyWalking 更是一個(gè)現(xiàn)代化的應(yīng)用程序性能監(jiān)控(Application Performance Monitoring)系統(tǒng), 尤其專為云原生、基于容器的分布式系統(tǒng)設(shè)計(jì).

2.架構(gòu)

2.1 架構(gòu)組件簡(jiǎn)介

1. 上部分Agent: 負(fù)責(zé)從應(yīng)用中,收集鏈路信息,發(fā)給Skywalking  oap 服務(wù)器.
2. 下部分Skywalking oap: 負(fù)責(zé)接收到Agent 發(fā)送的Tracing 的數(shù)據(jù)信息,然后進(jìn)行分析(Analysis platform) ,存儲(chǔ)到外部存儲(chǔ)器最終提供query  查詢功能.
3.左邊Storage: Tracing數(shù)據(jù)存儲(chǔ)，目前支持ES、MySQL、Sharding Sphere、TiDB、H2多種存儲(chǔ)器，目前采用較多的是ES，主要考慮是SkyWalking開發(fā)團(tuán)隊(duì)自己的生產(chǎn)環(huán)境采用ES為主.
4.右邊UI:負(fù)責(zé)提供控制臺(tái)，查看鏈路等等；

2.2 目錄簡(jiǎn)介

在這里插入圖片描述

3. 啟動(dòng)skywalking 默認(rèn)的配置服務(wù)

[root@basenode bin]# ./startup.sh 
SkyWalking OAP started successfully!
SkyWalking Web Application started successfully!
[root@basenode bin]# pwd
/opt/module/skywalking-apm-bin-es7/bin
[root@basenode bin]# 

4. 頁面訪問地址

http://192.168.1.180:8080/

在這里插入圖片描述

4.1 有時(shí)候8080 的端口被占用后, 我們可以修改端口

直接修改8080 端口

[root@basenode webapp]# pwd
/opt/module/skywalking-apm-bin-es7/webapp
[root@basenode skywalking-apm-bin-es7]# cd webapp/
[root@basenode webapp]# ll

5. 找一個(gè)spring boot 項(xiàng)目 運(yùn)行

命令:

java -javaagent:/opt/module/skywalking-apm-bin-es7/agent/skywalking-agent.jar -jar /opt/module/demo/user-center-0.0.1-SNAPSHOT.jar

5.1 然后訪問自己的spring boot 項(xiàng)目

在這里插入圖片描述

6. 然后看Syywalking

在這里插入圖片描述

7. 或者寫一個(gè)腳本

[root@basenode demo]# vi startup.sh 

#!/bin/sh
# SkyWalking Agent配置
export SW_AGENT_NAME=springboot-skywalking-wudl #Agent名字,一般使用`spring.application.name`
export SW_AGENT_COLLECTOR_BACKEND_SERVICES=192.168.1.180:11800 #配置 Collector 地址。
export SW_AGENT_SPAN_LIMIT=2000 #配置鏈路的最大Span數(shù)量，默認(rèn)為 300。
export JAVA_AGENT=-javaagent:/opt/module/skywalking-apm-bin-es7/agent/skywalking-agent.jar
java $JAVA_AGENT -jar /opt/module/demo/user-center-0.0.1-SNAPSHOT.jar #jar啟動(dòng)
