Question

我正在尝试使用Java（CloudWatch客户端）提取AWS实例指标。我能够提取CPUUtilization，MemoryAvailable等指标，但无法提取DiskSpaceUsed和DiskSpaceAvailable。我遵循的步骤是：

启动AWS实例

连接到实例并运行以下命令：

./mon-put-instance-data.pl --disk-path=/dev/xvda1 --disk-space-used
Successfully reported metrics to CloudWatch. Reference Id: 676e3970-d5d4-11e8-82a2-c732e192c2b2

./mon-put-instance-data.pl --disk-path=/dev/xvda1 --disk-space-used
Successfully reported metrics to CloudWatch. Reference Id: 6ad61d23-d5d4-11e8-9fdc-e5974e111635

Java代码如下：

private static GetMetricStatisticsRequest requestCustom(final String 
instanceId, final String metric)
        {
            final long twentyFourHrs = 1000 * 60 * 60 * 24;
            final int oneHour = 60 * 60;
            return new GetMetricStatisticsRequest()
                .withStartTime(new Date(new Date().getTime() - 
                 twentyFourHrs))
                .withNamespace("System/Linux").withPeriod(oneHour)
                .withDimensions(new Dimension().withName("InstanceId").withValue(instanceId))
                .withMetricName(metric).withStatistics("Average", "Maximum").withEndTime(new Date());


}

输出如下：

{Label: DiskSpaceUsed,Datapoints: []}
{Label: DiskSpaceAvailable,Datapoints: []}

我对MemoryUsed和MemoryAvailable度量遵循的相同过程。我正在获取MemoryUsed和MemoryAvailable的输出，但没有获取DiskSpaceUsed的输出。怎么了？

无法从CloudWatch提取DiskSpaceUsed / DiskSpaceAvailable指标
