Question

我希望能够获取我的集群的每小时平均CPUUtilization。但是使用amazononica时出现此错误：<html> <head> </head> <body> <svg id="svgOne" xmlns="http://www.w3.org/2000/svg" width="550" height="550"> </svg> <script type="text/javascript"> var svgns = "http://www.w3.org/2000/svg"; function rectan() { for (var i = 0; i < 5; i++) { var x = Math.floor(Math.random() * 200) + 1 ; y = Math.floor(Math.random() * 200) + 1 ; var rect = document.createElementNS(svgns, 'rect'); rect.setAttributeNS(null, 'x', x); rect.setAttributeNS(null, 'y', y); rect.setAttributeNS(null, 'height', '50'); rect.setAttributeNS(null, 'width', '50'); rect.setAttributeNS(null, 'fill', 'none'); rect.setAttributeNS(null, 'stroke', '#010101'); document.getElementById('svgOne').appendChild(rect); } } rectan(); </script> </body> </html>

com.amazonaws.services.cloudwatch.model.InvalidParameterValueException: The parameter StartTime must not equal parameter EndTime.

运行此aws cmd返回正确的指标，但是我想使用amazononica来执行此操作。

(get-metric-statistics {:metric-name "CPUUtilization"
                        :namespace "AWS/ECS"
                        :dimensions [{:name  "ClusterName" :value "my-cluster"}]
                        :start-time "2018-08-31T12:00:00Z"
                        :end-time "2018-08-31T13:00:00Z"
                        :statistics ["Average"]
                        :period 3600})

由于documentation：开始时间和：结束时间必须是Date对象。在您的示例中，它不适用于字符串。您也可以看看这个example

(let [date-string (.. (SimpleDateFormat. "MM-dd-yyyy")
                  (format (Date.)))]
   (get-metric-statistics
       ....
       :start-time (.minusDays (DateTime.) 1)
       :end-time date-string
       ...
      ))

如何获取群集的每小时平均CPU使用率？
