[GitHub] [servicecomb-java-chassis] liyupeisleep opened a new issue #1910: 实例隔离没有生效

liyupeisleep opened a new issue #1910:
URL: https://github.com/apache/servicecomb-java-chassis/issues/1910


   1、注册了三个服务端A、B、C，一个消费端。将消费端的实例隔离配置修改如下
   ![image](https://user-images.githubusercontent.com/67566979/89303170-67085e80-d69e-11ea-937c-005677b62551.png)
   2、服务端B方法内设置sleep，使其超时报490
   3、一分钟内触发多次，还是会有1/10左右的概率请求到B服务，报490

   ```
           serverStats.markIsolated(true);
           eventBus.post(
               new IsolationServerEvent(invocation, instance, serverStats,
                   settings, Type.OPEN, server.getEndpoint())); 
           LOGGER.warn("Isolate service {}'s instance {}.", invocation.getMicroserviceName(),
               instance.getInstanceId());
   ```
   
   可以查看 IsolationDiscoveryFilter 的细节。

   > 实例被隔离会打印日志和[发送隔离事件](https://docs.servicecomb.io/java-chassis/zh_CN/general-development/AlarmEvent/)
   > 
   > 有一定的请求到 B ， 我估计是因为 singleTestTime 的原因， 这个隔离时间较短， 5秒中可能尝试访问这个被隔离的实例一次。
   
   请问日志关键字是啥，我在消费端日志搜 isolation没结果

   负载均衡设置的权重策略。所以看着像负载均衡的策略，B实例怎么才能判断被隔离？
