@Generated(value="com.amazonaws:aws-java-sdk-code-generator") public interface AmazonCloudWatchAsync extends AmazonCloudWatch
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
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.

Gets statistics for the specified metric.
The maximum number of data points returned from a single call is 1,440. If you request more than 1,440 data points, CloudWatch returns an error. To reduce the number of data points, you can narrow the specified time range and make multiple requests across adjacent time ranges, or you can increase the specified period. Data points are not returned in chronological order.
CloudWatch aggregates data points based on the length of the period that you specify. For example, if you request statistics with a one-hour period, CloudWatch aggregates all data points with time stamps that fall within each one-hour period. Therefore, the number of values aggregated by CloudWatch is larger than the number of data points returned.
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.
Amazon CloudWatch retains metric data as follows:
Data points with a period of less than 60 seconds are available for 3 hours. These data points are
high-resolution metrics and are available only for custom metrics that have been defined with a
StorageResolution of 1.
Data points with a period of 60 seconds (1-minute) are available for 15 days.
Data points with a period of 300 seconds (5-minute) are available for 63 days.
Data points with a period of 3600 seconds (1 hour) are available for 455 days (15 months).
Data points that are initially published with a shorter period are aggregated together for long-term storage. For example, if you collect data using a period of 1 minute, the data remains available for 15 days with 1-minute resolution. After 15 days, this data is still available, but is aggregated and retrievable only with a resolution of 5 minutes. After 63 days, the data is further aggregated and is available with a resolution of 1 hour.
CloudWatch started retaining 5-minute and 1-hour metric data as of July 9, 2016.
For information about metrics and dimensions supported by AWS services, see the Amazon CloudWatch Metrics and Dimensions Reference in the Amazon CloudWatch User Guide.

Future<PutDashboardResult> putDashboardAsync(PutDashboardRequest putDashboardRequest)
Creates a dashboard if it does not already exist, or updates an existing dashboard. If you update a dashboard, the entire contents are replaced with what you specify here.
You can have up to 500 dashboards per account. All dashboards in your account are global, not region-specific.
A simple way to create a dashboard using PutDashboard is to copy an existing dashboard. To copy an
existing dashboard using the console, you can load the dashboard and then use the View/edit source command in the
Actions menu to display the JSON block for that dashboard. Another way to copy a dashboard is to use
GetDashboard, and then use the data returned within DashboardBody as the template for
the new dashboard when you call PutDashboard.
When you create a dashboard with PutDashboard, a good practice is to add a text widget at the top of
the dashboard with a message that the dashboard was created by script and should not be changed in the console.
This message could also point console users to the location of the DashboardBody script or the
CloudFormation template used to create the dashboard.

implementation of the callback methods in this interface to receive notification of successful or
unsuccessful completion of the operation.Future<PutMetricAlarmResult> putMetricAlarmAsync(PutMetricAlarmRequest putMetricAlarmRequest)
Creates or updates an alarm and associates it with the specified 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 state is set appropriately. Any actions associated with the state are then executed.
When you update an existing alarm, its state is left unchanged, but the update completely overwrites the previous configuration of the alarm.
If you are an IAM user, you must have Amazon EC2 permissions for some operations:
iam:CreateServiceLinkedRole for all alarms with EC2 actions
ec2:DescribeInstanceStatus and ec2:DescribeInstances for all alarms on 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 are not performed. However, if you are later granted the required permissions, the alarm actions that you created earlier are performed.
If you are using an IAM role (for example, an 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 AWS STS, you cannot stop or terminate an EC2 instance using alarm actions.
You must create at least one stop, terminate, or reboot alarm using either the Amazon EC2 or CloudWatch consoles to create the EC2ActionsAccess IAM role. After this IAM role is created, you can create stop, terminate, or reboot alarms using a command-line interface or API.

Publishes metric data points to Amazon CloudWatch. CloudWatch associates the data points with the specified metric. If the specified metric does not exist, CloudWatch creates the metric. When 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 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

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
putMetricDataRequest - asyncHandler - Asynchronous callback handler for events in the lifecycle of the request. Users can provide an
implementation of the callback methods in this interface to receive notification of successful or
unsuccessful completion of the operation.Future<SetAlarmStateResult> setAlarmStateAsync(SetAlarmStateRequest setAlarmStateRequest)
Temporarily sets the state of an alarm for testing purposes. When the updated state 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 state to ALARM
sends an SNS message. The alarm returns to its actual state (often within seconds). Because the alarm state
change happens quickly, it is typically only visible in the alarm's History tab in the Amazon CloudWatch
console or through DescribeAlarmHistory.
