换网ip变了

4.流控规则

直接



快速点击，超峰值


多次点击，无反应



关联



等线程结束后恢复正常


预热

5秒钟时间预热，从10/3达到10

快速点击，5秒以后不再报错


排队等待



慢调用比例



停止jmeter后正常


异常比例



停止jmeter后，点击一下


异常数

5.热点key限流

快速点击，超过每秒一次



快速点击，超过每秒一次

无p1，快速点击，超过每秒一次

参数例外项

当p1=5时，阈值200，快速点击，不会被限流

添加异常

6.系统规则

快速点击，超过每秒一次

7.SentinelResource配置

1

快速点击，超过每秒一次

关闭8401后

2

快速点击，超过每秒一次


3

快速点击，超过每秒一次

8.服务熔断

9003和9004配置一样
