通过Caliper进行压力测试程序

第一步. 配置基本环境

安装NodeJS  

 实战一：搭建本地链用caliper压测

第一步：搭链

 安装依赖

sudo apt install -y openssl curl

cd ~ && mkdir -p fisco && cd fisco
curl -#LO https://osp-1257653870.cos.ap-guangzhou.myqcloud.com/FISCO-BCOS/FISCO-BCOS/releases/v2.9.1/build_chain.sh && chmod u+x build_chain.sh

bash build_chain.sh -l 127.0.0.1:4 -p 30300,20200,8545

bash nodes/127.0.0.1/start_all.sh

  },
  "fisco-bcos": {

    },
    "network": {
      "nodes": [
        {

          "rpcPort": "8545",
          "channelPort": "20200" 
        },
        {
          "ip": "127.0.0.1",
          "rpcPort": "8546",
          "channelPort": "20201"
        },
        {

          "rpcPort": "8547",
          "channelPort": "20202"
        },
        {
          "ip": "127.0.0.1",
          "rpcPort": "8548",
          "channelPort": "20203"
        }
      ],

    ]
  },

}

 测试脚本文件介绍

测试配置文件位于./benchmarks/samples/fisco-bcos/helloworld/config.yaml

第三步，对本地四节点链进行测试

cd /home/myy/Desktop/benchmarks/caliper-benchmarks

npx caliper benchmark run --caliper-workspace /home/myy/Desktop/benchmarks/caliper-benchmarks --caliper-benchconfig /home/myy/Desktop/benchmarks/caliper-benchmarks/benchmarks/samples/fisco-bcos/helloworld/config.yaml --caliper-networkconfig /home/myy/Desktop/benchmarks/caliper-benchmarks/networks/fisco-bcos/test/fisco-bcos2.json

• --caliper-workspace：指定 Caliper 的工作空间路径，通常是包含 benchmark 配置和网络配置的目录路径。
• --caliper-benchconfig：指定要运行的基准测试的配置文件的路径。这个配置文件描述了性能测试的参数、交易的工作负载等。
• --caliper-networkconfig：指定网络配置文件的路径。这个文件描述了要连接的区块链网络的信息，如节点地址、身份验证等。

第四步：停止节点  

cd /root/fisco/nodes/127.0.0.1/stop_all.sh

通过Java SDK进行压力测试

第一步:安装JDK

sudo apt install openjdk-11-jdk
java --version

第二步编译源码

./gradlew build

第三步. 配置Demo

cd dist
cp -r ~/fisco/nodes/127.0.0.1/sdk/* conf

peers=["127.0.0.1:20200", "127.0.0.1:20201","127.0.0.1:20202","127.0.0.1:20203"]

 第四步. 执行示例压力测试程序

注意：你的本地链需要启动

cd dist
java -cp 'conf/:lib/*:apps/*' org.fisco.bcos.sdk.demo.perf.PerformanceOk 10000 1000 1
