sentinel

模块用途

sentinel模块源自阿里开源的sentinel，相关文档如下：

• https://github.com/alibaba/sentinel-golang/wiki
• https://sentinelguard.io/zh-cn/docs/golang/basic-api-usage.html

ngo做了简单的封装，集成了哨兵监控

使用说明

配置

参数配置详见sentinel options

调用

v0.1.57版本之前的配置将被弃用

circuitbreaker:
  rules:
    - resource: count
      strategy: 2
      retryTimeoutMs: 30
      minRequestAmount: 1
      statIntervalMs: 5000
      maxAllowedRtMs: 10
      threshold: 1.0
    - resource: ratio
      strategy: 1
      retryTimeoutMs: 30
      minRequestAmount: 10
      statIntervalMs: 5000
      maxAllowedRtMs: 10
      threshold: 1.0

新配置如下:

sentinel:
  circuitbreakerRules:
    - resource: count
      strategy: 2
      retryTimeoutMs: 30
      minRequestAmount: 1
      statIntervalMs: 5000
      maxAllowedRtMs: 10
      threshold: 1.0
    - resource: ratio
      strategy: 1
      retryTimeoutMs: 30
      minRequestAmount: 10
      statIntervalMs: 5000
      maxAllowedRtMs: 10
      threshold: 1.0
  flowRules:
  hotspotRules:
  isolationRules:
  systemRules:

规则参数描述，在官方文档中已经写的很清楚了，这里不在配置文件上加了。

import github.com/NetEase-Media/ngo/adapter/sentinel

sentinel.Entry("abc")
sentinel.TraceError(entry, err)

注意事项

• 业务调用请务必使用ngo包里的Entry和TraceError方法，否则哨兵无法监控
