jvm-sandbox-repeater学习笔记 1

安装

git clone https://github.com/alibaba/jvm-sandbox-repeater.git
cd jvm-sandbox-repeater/bin
./bootstrap.sh

执行完成后应该会在用户根目录cd ~生成一个 sandbox 目录，而且会启动一个 SpringBoot （Demo）应用（启动失败也无所谓，直接用本身的Java应用更方便）

也能够直接执行curl -s http://sandbox-ecological.oss-cn-hangzhou.aliyuncs.com/install-repeater.sh | sh 仅安装 sandbox，不部署 Demo 应用

配置

    "java-subInvoke",
    "mybatis",
    "ibatis",
    "dubbo-provider",
    "dubbo-consumer"
  ],
  "repeatIdentities": [
    "java",
    "http"
  ],
  "sampleRate": 10000,
  "useTtl": true
}

说明

<style> table th:first-of-type { width: 150px; } </style>

配置项	释义
useTtl	是否开启ttl线程上下文切换，开启以后，才能将并发线程中发生的子调用记录下来，不然没法录制到并发子线程的子调用信息
degrade	是否执行录制降级策略，开启以后，不进行录制，只处理回放请求
exceptionThreshold	异常发生阈值；默认1000
sampleRate	采样率；最小力度万分之一；默认值：10000
pluginsPath	插件地址
httpEntrancePatterns	因为HTTP接口的量太大（先后端未分离的状况可能还有静态资源）所以必须走白名单匹配模式才录制
javaEntranceBehaviors	java入口插件动态加强的行为
javaSubInvokeBehaviors	java子调用插件动态加强的行为
pluginIdentities	须要启动的插件
repeatIdentities	回放器插件

示例

该配置实现了对/perf路径下接口的录制； mock了JPA中的两个mongo查询方法； cat ~/.sandbox-module/cfg/repeater-config.json
