Question

我正在尝试使用CloudWatch获取特定亚马逊EC2实例的CPU百分比

我在执行代码时遇到此错误（见下文）

服务AmazonEC2的请求版本（2010-08-01）不存在“

我无法更改AmazonCloudWatchClient中的ServiceVersion，因为它有Read Only property

默认设置为2010-08-01

我需要将ServiceVersion更改为2014-10-01

请查看以下配置

此处配置文字

  var client = new AmazonCloudWatchClient(clientkey,secretkey,new     AmazonCloudWatchConfig{ServiceURL="url"})
  var dimension = new Dimension
        {
            Name = "instanceName",
            Value = "instanceID"
        };
  var request = new GetMetricStatisticsRequest
        {
            Dimensions = new List<Dimension>() { dimension },
            EndTime = DateTime.Today,
            MetricName = "CPUUtilization",
            Namespace = "AWS/EC2",
            // Get statistics by day.
            Period = (int)TimeSpan.FromDays(1).TotalSeconds,
            // Get statistics for the past month.
            StartTime = DateTime.Today.Subtract(TimeSpan.FromDays(30)),
            Statistics = new List<string>() { "Minimum" },
            Unit = StandardUnit.Percent              
        };

  var response = client.GetMetricStatistics(request);

        if (response.Datapoints.Count > 0)
        {
            foreach (var point in response.Datapoints)
            {
                Console.WriteLine(point.Timestamp.ToShortDateString() +
                  " " + point.Minimum + "%");
            }
        }

为什么你认为你需要改变日期？

该属性确实没有setter（请参阅code），因此您将无法使用此类属性定义配置。

我知道你不想透露你的信息，但你有什么

  var dimension = new Dimension
        {
            Name = "instanceName",
            Value = "instanceID"
        };

名称应为InstanceName，如果您使用实例ID，则在值中指示它应该是InstanceId类似

  var dimension = new Dimension
        {
            Name = "InstanceId"
            Value = "i-54cfb999"
        };
