/**
* Interface for accessing CloudWatch asynchronously. Each asynchronous method will return a Java Future object
* representing the asynchronous operation; overloads which accept an {@code AsyncHandler} can be used to receive
* notification when an asynchronous operation completes.
*
* Note: Do not directly implement this interface, new methods are added to it regularly. Extend from
* {@link com.amazonaws.services.cloudwatch.AbstractAmazonCloudWatchAsync} instead.
*
*
*
* Amazon CloudWatch monitors your Amazon Web Services (AWS) resources and the applications you run on AWS in real time.
* You can use CloudWatch to collect and track metrics, which are the variables you want to measure for your resources
* and applications.
*
*
* CloudWatch alarms send notifications or automatically change the resources you are monitoring based on rules that you
* define. For example, you can monitor the CPU usage and disk reads and writes of your Amazon EC2 instances. Then, use
* this data to determine whether you should launch additional instances to handle increased load. You can also use this
* data to stop under-used instances to save money.
*
*
* In addition to monitoring the built-in metrics that come with AWS, you can monitor your own custom metrics. With
* CloudWatch, you gain system-wide visibility into resource utilization, application performance, and operational
* health.

* Each PutMetricData request is limited to 40 KB in size for HTTP POST requests.
*
*
* Although the Value parameter accepts numbers of type Double, CloudWatch rejects values
* that are either too small or too large. Values must be in the range of 8.515920e-109 to 1.174271e+108 (Base 10)
* or 2e-360 to 2e360 (Base 2). In addition, special values (for example, NaN, +Infinity, -Infinity) are not
* supported.
*
*
* You can use up to 10 dimensions per metric to further clarify what data the metric collects. For more information
* about specifying dimensions, see Publishing
* Metrics in the Amazon CloudWatch User Guide.
*
*
* Data points with time stamps from 24 hours ago or longer can take at least 48 hours to become available for
* GetMetricStatistics from the time they are submitted.
*
*
* CloudWatch needs raw data points to calculate percentile statistics. If you publish data using a statistic set
* instead, you can only retrieve percentile statistics for this data if one of the following conditions is true:
*
*
* -
*
* The SampleCount value of the statistic set is 1
*
*
* -
*
* The Min and the Max values of the statistic set are equal
