@ThreadSafe public class AmazonCloudWatchAsyncClient extends AmazonCloudWatchClient implements AmazonCloudWatchAsync
AsyncHandler can be used to receive
notification when an asynchronous operation completes.
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 make changes to 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 Elastic Compute Cloud (Amazon EC2) instances and 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.

AmazonCloudWatchAsyncGets statistics for the specified metric.
The maximum number of data points that can be queried is 50,850, whereas
the maximum number of data points returned from a single
GetMetricStatistics request is 1,440. If you make a request
that generates more than 1,440 data points, Amazon CloudWatch returns an
error. In such a case, you can alter the request by narrowing the
specified time range or increasing the specified period. Alternatively,
you can make multiple requests across adjacent time ranges.
GetMetricStatistics does not return the data in
chronological order.
Amazon CloudWatch aggregates data points based on the length of the
period that you specify. For example, if you request
statistics with a one-minute granularity, Amazon CloudWatch aggregates
data points with time stamps that fall within the same one-minute period.
In such a case, the data points queried can greatly outnumber the data
points returned.
The following examples show various statistics allowed by the data point
query maximum of 50,850 when you call GetMetricStatistics on
Amazon EC2 instances with detailed (one-minute) monitoring enabled:
For information about the namespace, metric names, and dimensions that other Amazon Web Services products use to send metrics to CloudWatch, go to Amazon CloudWatch Metrics, Namespaces, and Dimensions Reference in the Amazon CloudWatch Developer Guide.

AmazonCloudWatchAsyncCreates or updates an alarm and associates it with the specified Amazon CloudWatch metric. Optionally, this operation can associate one or more Amazon Simple Notification Service resources with the alarm.
When this operation creates an alarm, the alarm state is immediately set
to INSUFFICIENT_DATA. The alarm is evaluated and its
StateValue is set appropriately. Any actions associated with
the StateValue is then executed.

However, if you are later granted permission to use the associated Amazon EC2 APIs, the alarm actions you created earlier will be performed. For more information about IAM permissions, see Permissions and Policies in Using IAM.
If you are using an IAM role (e.g., an Amazon EC2 instance profile), you cannot stop or terminate the instance using alarm actions. However, you can still see the alarm state and perform any other actions such as Amazon SNS notifications or Auto Scaling policies.
If you are using temporary security credentials granted using the AWS Security Token Service (AWS STS), you cannot stop or terminate an Amazon EC2 instance using alarm actions.

If the specified metric does not exist, Amazon CloudWatch creates the metric. When Amazon CloudWatch creates a metric, it can take up to fifteen minutes for the metric to appear in calls to the ListMetrics action.

AmazonCloudWatchAsync
Temporarily sets the state of an alarm. When the updated
StateValue differs from the previous value, the action
configured for the appropriate state is invoked. For example, if your
alarm is configured to send an Amazon SNS message when an alarm is
triggered, temporarily changing the alarm's state to ALARM will
send an Amazon SNS message. This is not a permanent change. The next
periodic alarm check (in about a minute) will set the alarm to its actual
state. Because the alarm state change happens very quickly, it is
typically only visibile in the alarm's History tab in the Amazon
CloudWatch console or through DescribeAlarmHistory.
