在后台拉取镜像启动容器docker-compose up -d
确认ElasticSearch,kibana启动成功2. 使用ASP.NET Core和NLog向ES发送日志VS Code创建.NetCore程序dotnet new mvc --no-https -o Elastic.Kibana.NLog
cd Elastic.Kibana.NLog
添加NLog依赖包dotnet add package NLog
dotnet add package NLog.Web.AspNetCore
dotnet add package NLog.Targets.ElasticSearch
添加nlog.config文件黄色背景行是NLog直接向ES发送日志的核心配置。?xml version1.0 encodingutf-8 ?

/nlog
ASP.NET Core添加Nlog并输出日志 public class Program{public static void Main(string[] args){var webHost WebHost.CreateDefaultBuilder(args).ConfigureLogging((hostingContext, loggingBuilder) {loggingBuilder.AddConsole(x x.IncludeScopes true).AddDebug();}).UseNLog().UseStartupStartup().Build();webHost.Run();}}
Controller自定义日志public class HomeController : Controller{private readonly ILoggerHomeController _logger;public HomeController(ILoggerHomeController logger){_logger logger;}public IActionResult Index(){_logger.LogInformation(HomeController Index executed at {date}, DateTime.UtcNow);return View();}}
3.在kibana中创建Index Patterndotnet run启动ASP.NET Core程序现在开始产生日志。Kibana使用index pattern从ElasticSearch indices中获取数据。要在Kibana中显示日志需要先定义index pattern:之后选择timestamp时间过滤。回到Discovery界面可以看到所有日志。ok, 上面便是ASP.NET CoreNLog集成ES、Kibana的基本操作流程。看起来很简单其实只是九牛一毛Elastic Stack的内功博大精深关注我解锁各种实战姿势。ASP.NET Core端点路由 作用原理[温故知新] 编程原则和模式ASP.NET Core结合Redis实践消息队列Quartz.net在集群环境下部署任务的姿势分享我在前后端分离项目中Gitlab-CI的经验
