```
@ThreadSafe
public class AmazonCloudWatchAsyncClient
extends AmazonCloudWatchClient
implements AmazonCloudWatchAsync
```
Interface for accessing CloudWatch asynchronously. Each asynchronous method will return a Java Future object representing the asynchronous operation; overloads which accept an 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.

    Gets 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. A period can be as short as one minute (60 seconds) or as long as one day (86,400 seconds). 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:
    - Statistics for up to 400 instances for a span of one hour
    - Statistics for up to 35 instances over a span of 24 hours
    - Statistics for up to 2 instances over a span of 2 weeks

    Description copied from interface: AmazonCloudWatchAsync
    
    Returns a list of valid metrics stored for the AWS account owner. Returned metrics can be used with GetMetricStatistics to obtain statistical data for a given metric.

  - putMetricAlarmAsync
```
public Future<PutMetricAlarmResult> putMetricAlarmAsync(PutMetricAlarmRequest request)
```
    Description copied from interface: AmazonCloudWatchAsync
    Creates or updates an alarm and associates it with the specified Amazon CloudWatch metric. Optionally, this operation can associate one or more Amazon SNS 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 are then executed.
    
    When updating an existing alarm, its StateValue is left unchanged, but it completely overwrites the alarm's previous configuration.
    If you are using an AWS Identity and Access Management (IAM) account to create or modify an alarm, you must have the following Amazon EC2 permissions:
    
    ec2:DescribeInstanceStatus and ec2:DescribeInstances for all alarms on Amazon EC2 instance status metrics.
    
    ec2:StopInstances for alarms with stop actions.
    
    ec2:TerminateInstances for alarms with terminate actions.
    
    ec2:DescribeInstanceRecoveryAttribute, and ec2:RecoverInstances for alarms with recover actions.
    
    If you have read/write permissions for Amazon CloudWatch but not for Amazon EC2, you can still create an alarm but the stop or terminate actions won't be performed on the Amazon EC2 instance. 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.

  - putMetricDataAsync
```
public Future<PutMetricDataResult> putMetricDataAsync(PutMetricDataRequest request)
```
    Description copied from interface: AmazonCloudWatchAsync
    
    Publishes metric data points to Amazon CloudWatch. Amazon CloudWatch associates the data points with the specified metric. 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 ListMetrics.
    
    Each PutMetricData request is limited to 8 KB in size for HTTP GET requests and is limited to 40 KB in size for HTTP POST requests.
    
    Although the Value parameter accepts numbers of type Double, Amazon 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 (e.g., NaN, +Infinity, -Infinity) are not supported.
    
    Data that is timestamped 24 hours or more in the past may take in excess of 48 hours to become available from submission time using GetMetricStatistics.
    
    Specified by:

  - setAlarmStateAsync
```
public Future<SetAlarmStateResult> setAlarmStateAsync(SetAlarmStateRequest request)
```
    Description copied from interface: AmazonCloudWatchAsync
    
    Temporarily sets the state of an alarm for testing purposes. 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 sends an Amazon SNS message. The alarm returns to its actual state (often within seconds). Because the alarm state change happens very quickly, it is typically only visible in the alarm's History tab in the Amazon CloudWatch console or through DescribeAlarmHistory.
    
    Specified by:
    
    setAlarmStateAsync in interface AmazonCloudWatchAsync
    
    Parameters:
    
    request - Describes the inputs for SetAlarmState.
    
    Returns:
    
    A Java Future containing the result of the SetAlarmState operation returned by the service.
