前言：Hyperledger  caliper 的本质是使用node对被测试网络进行压力测试，因此需要nodejs。本次使用 Hyperledger caliper 0.5 对 fabric 1.4.6进行压测

准备条件：nodejs 16 （略 linux下 解压+环境变量即可）

# 创建工作目录
mkdir /opt/fabric/caliper
# 进入工作目录
cd /opt/fabric/caliper
# 安装 caliper CLI, （如果慢 可以使用代理  sudo npm config set https-proxy http://172.16.10.34:7890）
npm install --only=prod @hyperledger/caliper-cli@0.5.0 

配置文件（放在工作空间中：/root/fabric/caliper）

network-config.yaml （配置要测试的网络和组织信息）

connection-org1.yaml (配置组织的连接信息)

benchmark-config.yaml （配置压力测试的参数）

test:workers:number: 5rounds:- label: Query map.txDuration: 30rateControl:type: fixed-loadopts:transactionLoad: 1000workload:module: workload/query.jsarguments:assets: 2

query.js (在子目录下，绝对路径为：/root/fabric/caliperworkload/query.js) 根据业务编写查询方法或插入方法

'use strict';const { WorkloadModuleBase } = require('@hyperledger/caliper-core');class QueryAssetWorkload extends WorkloadModuleBase {constructor() {super();}async initializeWorkloadModule(workerIndex, totalWorkers, roundIndex, roundArguments, sutAdapter, sutContext) {await super.initializeWorkloadModule(workerIndex, totalWorkers, roundIndex, roundArguments, sutAdapter, sutContext);}async submitTransaction() {await this.sutAdapter.sendRequests({contractId: 'ccmap',  // 你的链码名称contractFunction: 'query', // 查询方法contractArguments: ["a"],readOnly: true});}
} module.exports.createWorkloadModule = () => new QueryAssetWorkload();

执行

 npx caliper launch manager   --caliper-workspace .   --caliper-benchconfig /opt/fabric/caliper/benchmark-config.yaml   --caliper-networkconfig /opt/fabric/caliper/network-config.yaml  --caliper-flow-only-test --caliper-fabric-gateway-enabled

测试效果如下
