Skywalking Demo
参考 https://www.cnblogs.com/fallTakeMan/p/13437215.html
SkyWalking 是观察性分析平台和应用性能管理系统。提供分布式追踪、服务网格遥测分析、度量聚合和可视化一体化解决方案。支持Java, .Net Core, PHP, NodeJS, Golang, LUA语言探针,支持Envoy + Istio构建的Service Mesh。
这里抛出两个概念,SkyWalking 服务和语言探针。SkyWalking 本身是用 Java 写的,作为应用性能管理系统,探针是收集应用性能指标数据的,比如在 .net core 项目中引入 SkyAPM.Agent.AspNetCore,做一些配置,就可以将该项目的数据报告给 SkyWalking 服务,在 SkyWalking UI 界面看到可视化的数据。
SkyWalking 展示的数据是需要存储的,默认是 H2,同时也支持使用ElasticSearch、MySQL、TiDB、InfluxDB,这里使用 elasticsearch。
1.docker compose 进行安装

2.创建webapi 项目添加nuget包和配置文件
dotnet new webapi -n sampleapp cd sampleapp dotnet add package SkyAPM.Agent.AspNetCore set ASPNETCORE_HOSTINGSTARTUPASSEMBLIES=SkyAPM.Agent.AspNetCore set SKYWALKING__SERVICENAME=sample_app
3.添加CLI和配置文件config
#Install SkyAPM.DotNet.CLI dotnet tool install -g SkyAPM.DotNet.CLI #Use dotnet skyapm config [your_service_name] [your_servers] to generate config file. dotnet skyapm config sample_app 172.24.16.1:11800
4.运行项目
dotnet run
5.查看UI
本机访问 SkyWalking 服务地址,UI 暴露端口是 8080.
