通过Azure App Service门户,启用Health Check来监视应用服务的实例,当发现其中一个实例处于不健康(unhealthy)状态时,通过重新路由(即把有问题的实例从负载均衡器中移除, Load Balancer)的方式把请求发送到健康的实例上。并且如果不健康的实例一直存在问题,系统则会启动一个新实例来替换不健康的这个实例。 This article ...

扩展实例时，App Service 会通过配置的 URL 进行测试，确保实例准备接受业务请求。Health Check 不支持 302 重定向，并且每小时最多替换一个实例，每天最多替换三个实例。启用 Health Check 会重启当前应用程序，建议先配置在 Staging slots，并通过交换部署槽发布到生产环境。若需修改默认配置，可通过应用...
To address this situation, we began previewing Health Check last year. The Health Check feature allows you to specify a path on your application for App Service to ping. If an instance fails to respond to the ping, the system determines it isunhealthyand removes it from the load balancer ro...

What App Service does with Health checks When given a path on your app, Health check pings this path on all instances of your App Service app at 1-minute intervals. If a web app that's running on a given instance doesn't respond with a status code between 200-299 (inclusive) after ...
ok,我们非常简单的在项目中引用了HealthCheck,当我们的api运行后,我们只需要通过 http://xxx/hc 就能对这个api进行Health Check了。 写在最后 今天我们了解了Health Check,并简单看了它在eShop中的使用。目前看来还不是很完善,只在其他service或者app调用其Health Check接口的时候才能进行检测,当然我们可以改造下,使...
Each check has configurable Period and Grace Time parameters. Period is the expected time between pings. Grace Time specifies how long to wait before sending out alerts when a job is running late. Alternatively, you can define the expected schedules using a cron expressions. Healthchecks uses the...
Health checks can test an app's dependencies, such as databases and external service endpoints, to confirm availability and normal functioning. Health checks are typically used with an external monitoring service or container orchestrator to check the status of an app. Before adding health checks to...
