如何使用node.js函数检查我的vm实例在google-cloud中使用了多少CPU和内存

npm install @google-cloud/monitoring

const { MetricServiceClient } = require('@google-cloud/monitoring');

const projectId = 'YOUR_PROJECT_ID';
const instanceId = 'YOUR_INSTANCE_ID';

const client = new MetricServiceClient();

async function getCpuUsage() {
  const request = {
    name: client.projectPath(projectId),
    filter: `metric.type="compute.googleapis.com/instance/cpu/utilization" resource.labels.instance_id="${instanceId}"`,
    interval: {
      startTime: {
        seconds: Date.now() / 1000 - 3600, // 从过去一小时开始
      },
      endTime: {
        seconds: Date.now() / 1000,
      },
    },
    view: 'FULL',
  };

  const [response] = await client.listTimeSeries(request);
  console.log('CPU Usage:', response);
}

getCpuUsage().catch(console.error);

async function getMemoryUsage() {
  const request = {
    name: client.projectPath(projectId),
    filter: `metric.type="compute.googleapis.com/instance/memory/usage" resource.labels.instance_id="${instanceId}"`,
    interval: {
      startTime: {
        seconds: Date.now() / 1000 - 3600, // 从过去一小时开始
      },
      endTime: {
        seconds: Date.now() / 1000,
      },
    },
    view: 'FULL',
  };

  const [response] = await client.listTimeSeries(request);
  console.log('Memory Usage:', response);
}

getMemoryUsage().catch(console.error);
