1. skywalking
官網:https://skywalking.apache.org/
特點:
1.SkyWalking: 一個開源的可觀測平臺, 用于從服務和云原生基礎設施收集, 分析, 聚合及可視化數據。
2.SkyWalking 更是一個現代化的應用程序性能監控(Application Performance Monitoring)系統, 尤其專為云原生、基于容器的分布式系統設計.
2.架構
skywalking.png
2.1 架構組件簡介
1. 上部分Agent: 負責從應用中,收集鏈路信息,發給Skywalking oap 服務器.
2. 下部分Skywalking oap: 負責接收到Agent 發送的Tracing 的數據信息,然后進行分析(Analysis platform) ,存儲到外部存儲器最終提供query 查詢功能.
3.左邊Storage: Tracing數據存儲，目前支持ES、MySQL、Sharding Sphere、TiDB、H2多種存儲器，目前采用較多的是ES，主要考慮是SkyWalking開發團隊自己的生產環境采用ES為主.
4.右邊UI:負責提供控制臺，查看鏈路等等；
2.2 目錄簡介
在這里插入圖片描述
3. 啟動skywalking 默認的配置服務
[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spring boot 項目 運行
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數量，默認為 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
7.1 運行 : sh startup.sh
[root@basenode demo]# sh startup.sh
