{...services.AddHealthChecks();
}
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{...app.UseHealthChecks(/health);
}我们甚至可以为第三方组件比如数据库、缓存提供健康状态检查。最后访问/health来查看应用程序的健康状态这种文本方式不够直观今天我们介绍一个轻量级的图形UI通过可视化的方式进行健康检查。Demo1.引用Nuget包引用如下Nuget包AspNetCore.HealthChecks.UI
AspNetCore.HealthChecks.UI.Client
AspNetCore.HealthChecks.UI.InMemory.StorageUI支持不同的存储类型如Sql Server、MySql等这里选择直接保存到内存。2.修改Startup.cs添加UI并设置了自定义健康检查用于演示不健康状态:public void ConfigureServices(IServiceCollection services)
{...services.AddHealthChecksUI().AddInMemoryStorage();services.AddHealthChecks().AddCheckDemoHealthCheck(My IO);
}public class DemoHealthCheck: IHealthCheck
{public TaskHealthCheckResult CheckHealthAsync(HealthCheckContext context, CancellationToken cancellationToken default){if (DateTime.Now.Second 30){return Task.FromResult(HealthCheckResult.Healthy());}return Task.FromResult(HealthCheckResult.Unhealthy(不健康));}
}指定健康检查和UI的地址并且使用UIResponseWriter.WriteHealthCheckUIResponse返回json格式健康检查数据public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{...app.UseEndpoints(endpoints {endpoints.MapControllers();endpoints.MapHealthChecks(/health, new HealthCheckOptions(){Predicate _ true,ResponseWriter UIResponseWriter.WriteHealthCheckUIResponse});endpoints.MapHealthChecksUI(options options.UIPath /health-ui);});
}3.添加配置项修改appsettings.json文件HealthChecksUI: {HealthChecks: [{Name: My IO,Uri: /health}],Webhooks: [{Name: ,Uri: ,Payload: ,RestoredPayload: }],EvaluationTimeinSeconds: 10,MinimumSecondsBetweenFailureNotifications: 60}HealthChecks是个数组也就是说UI同时可以监控多个健康检查API。Webhooks用于当API的健康状态改变时向指定Uri发送告警数据。4.使用运行程序访问/health-ui即可打开UI点击Details按钮还可查看健康状态历史
