Question

我有代码node.js，我尝试从AWS获取指标数据，但我有错误。我在互联网上搜索但没有任何相同的问题。这是我的源代码：

function getCloudwatchMetricData(queueName, callback) {
console.log("Get CloudWatch metric data of SQS: " + queueName);
var params = {
    MetricDataQueries: [{
        Id: queueName,
        MetricStat: {
            Metric: {
                Dimensions: [{
                    Name: 'QueueName',
                    Value: queueName
                }, ],
                MetricName: 'ApproximateNumberOfMessagesVisible',
                Namespace: 'AWS/SQS'
            },
            Period: 300,
            Stat: 'Average',
            Unit: 'Count'
        },
        ReturnData: true
    }, ],
    StartTime: startTime,
    EndTime: endTime,
    ScanBy: 'TimestampAscending'
};
cloudwatchClient.getMetricData(params, function (err, data) {
    if (err) console.log(err, err.stack); // an error occurred
    else console.log(data); // successful response
});
}

这是我的错误：

TypeError: cloudwatchClient.getMetricData is not a function

我尝试使用AWS CLI。它运行正常这是CLI命令：

aws cloudwatch get-metric-data --metric-data-queries file://testdata/metric-data-queries.json --start-time 2018-05-20T00:00:00Z --end-time 2018-05-21T00:00:00Z --scan-by TimestampAscending

如果有任何想法或同样的问题，请帮助我。这是指南： https://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/CloudWatch.html#getMetricData-property

注意：我不想使用动作“getMetricStatistics” 感谢

我首先要检查的是SDK版本参考。您可能正在参考最新的文档，但是您添加的脚本参考可能很旧。

请检查SDK参考的版本。

<script src="https://sdk.amazonaws.com/js/aws-sdk-2.326.0.min.js"></script>

AWS SKD node.js - getMetricData不是函数
