SkyWalking + Windows2019 + .NetCore3.1

    1.Downloads | Apache SkyWalking

    2.下载位置：

    3.下载后如图：

    1.文件: E:NetCoreSkywalkingapache-skywalking-apm-bin-es7webappwebapp.yml

    2.内容:

server:
  port: 18080

    1.下载:mysql-connector-java-8.0.28.jar到oap-libs下 版本的不同，直接影响数据表是否创建成功

     3.打开 E:NetCoreSkywalkingapache-skywalking-apm-bin-es7configapplication.yml 

     4.注释H2，开启mysql

    5.接着，到Mysql中创建一个  swtest数据库 

    6.执行 E:NetCoreSkywalkingapache-skywalking-apm-bin-es7binoapServiceInit.bat

    7.最后数据库表

http://localhost:18080

五.Net Core集成

    1.添加.net webapid项目 SkyAPM.Agent.AspNetCore 1.3

     2.Startup类中注册

 public void ConfigureServices(IServiceCollection services)
  {
            services.AddControllers();
 
            services.AddSkyAPM(ext => ext.AddAspNetCoreHosting());
 
  }

     3.添加配置文件:skyapm.json

    4.skyapm.json内容,ServiceName默认是项目名称

{
  "SkyWalking": {
    "ServiceName": "SkyWalkingDemo",
    "Namespace": "",
    "HeaderVersions": [
      "sw8"
    ],
    "Sampling": {
      "SamplePer3Secs": -1,
      "Percentage": -1.0
    },
    "Logging": {
      "Level": "Information",
      "FilePath": "logs\skyapm-{Date}.log"
    },
    "Transport": {
      "Interval": 3000,
      "ProtocolVersion": "v8",
      "QueueSize": 30000,
      "BatchSize": 3000,
      "gRPC": {
        "Servers": "127.0.0.1:11800",
        "Timeout": 10000,
        "ConnectTimeout": 10000,
        "ReportTimeout": 600000,
        "Authentication": ""
      }
    }
  }
}

    5.launchSettings.json 文件中添加服务名

"IIS Express": {
      "commandName": "IISExpress",
      "launchBrowser": true,
      "launchUrl": "weatherforecast",
      "environmentVariables": {
        "ASPNETCORE_ENVIRONMENT": "Development",
        "ASPNETCORE_HOSTINGSTARTUPASSEMBLIES": "SkyAPM.Agent.AspNetCore", // 必须配置
        "SKYWALKING__SERVICENAME": "SkyWalkingDemo" // 必须配置，在skywalking做标识
      }
    },

    6.在webapi中添加IEntrySegmentContextAccessor

private readonly IEntrySegmentContextAccessor segContext;
private readonly ILogger _logger;

 public WeatherForecastController(IEntrySegmentContextAccessor segContext,
            ILogger logger)
{
            this.segContext = segContext;
            _logger = logger;
}

 [HttpGet("Get1")]
public IActionResult Get1()
{
            //获取全局的skywalking的TracId
            var TraceId = segContext.Context.TraceId;      
            segContext.Context.Span.AddLog(LogEvent.Message($"SkywalkingTest1---Worker running at: {DateTime.Now}")); 
            segContext.Context.Span.AddLog(LogEvent.Message($"SkywalkingTest1---Worker running at--end: {DateTime.Now}"));

            return Ok($"TraceId={TraceId} ");
}

    ​7.运行项目，访问 http://localhost:46696/weatherforecast/get1

    8.​.最后访问 localhost:18080 进入追踪
