以下配置用于使用超级账本卡尺（0.4.2）监控位于远程机器中的 docker 容器的资源利用率。

test:
    name: sample fabric network
    description: sample Network Benchmark
    workers:
      type: local
      number: 5
    rounds:
      - label: readAsset
        description: Using Chaincode Asset Management contract
        txNumber: 10000
        rateControl: 
          type: fixed-load
          opts:
            tps: 200
        workload:
          module: workload/readAsset.js
          arguments:
            contractId: asset-management
monitors:
  resource:
  - module: docker
    options:
      interval: 5
      containers:
         - http://34.233.177.187:7051/peer0.org1.example.com

它给出如下错误，Error retrieving remote containers: Error: socket hang up并且不会生成任何与资源监控相关的报告。虽然，事务是使用 caliper 提交到远程网络的，我试图从那里监控容器 peer0.org1.example.com 的资源利用率。上面定义的机器 IP 和容器的名称在连接配置文件中定义。

从卡尺控制台记录

当使用本地机器完成监控时，它就可以工作了。为此，我使用了以下配置，并且它成功地用于本地 docker 容器。配置如下图所示：

monitors:
  resource:
  - module: docker
    options:
      interval: 5
      containers:
        - all

是否有更多配置可以监控 caliper 中的远程容器资源利用率？

谢谢！

Caliper 使用 dockerode@3.1.0 模块连接到容器（https://www.npmjs.com/package/dockerode），套接字挂起表示由于超时或类似原因未能创建连接。

有两种选择：

  1. 调试基于 dockerode 的连接 - 也许增加 caliper 中的日志级别会有所帮助？使用 dockerode@3.1.0 制作一个小应用程序来检查它连接到传递的容器 URL 的能力相对容易——如果你能够连接，并且相同的 URL 在 caliper 中不起作用，那么有需要修复的错误
  2. 换成基于 Prometheus 的监视器，它使用 CAdvisor 来监视容器统计信息（您也可以在这里免费获得 Grafana）
