如何获取集群的每小时平均 CPUUtilization？

Question

我希望能够获取集群的每小时平均 CPUUtilization。但是使用亚马逊我得到这个错误：com.amazonaws.services.cloudwatch.model.InvalidParameterValueException: The parameter StartTime must not equal parameter EndTime.

(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})

运行这个 aws cmd returns 是正确的指标，但我想用 amazonica 来做这个。

aws cloudwatch 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 :start-time and :end-time must be a Date object. It does not work with string in your example. You can also take a look at this example

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