AmazonCloudWatchAsyncDeletes the specified alarms. You can delete up to 100 alarms in one operation. However, this total can include no more than one composite alarm. For example, you could delete 99 metric alarms and one composite alarms with one operation, but you can't delete two composite alarms with one operation.
In the event of an error, no alarms are deleted.
It is possible to create a loop or cycle of composite alarms, where composite alarm A depends on composite alarm B, and composite alarm B also depends on composite alarm A. In this scenario, you can't delete any composite alarm that is part of the cycle because there is always still a composite alarm that depends on that alarm that you want to delete.
To get out of such a situation, you must break the cycle by changing the rule of one of the composite alarms in
the cycle to remove a dependency that creates the cycle. The simplest change to make to break a cycle is to
change the AlarmRule of one of the alarms to False.
Additionally, the evaluation of composite alarms stops if CloudWatch detects a cycle in the evaluation path.

You can use the GetMetricData API to retrieve as many as 500 different metrics in a single request,
with a total of as many as 100,800 data points. You can also optionally perform math expressions on the values of
the returned statistics, to create new time series that represent new insights into your data. For example, using
Lambda metrics, you could divide the Errors metric by the Invocations metric to get an error rate time series.
For more information about metric math expressions, see Metric Math Syntax and Functions in the Amazon CloudWatch User Guide.
Calls to the GetMetricData API have a different pricing structure than calls to
GetMetricStatistics. For more information about pricing, see Amazon CloudWatch Pricing.
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.
If you omit Unit in your request, all data that was collected with any unit is returned, along with
the corresponding units that were specified when the data was reported to CloudWatch. If you specify a unit, the
operation returns only data that was collected with that unit specified. If you specify a unit that does not
match the data collected, the results of the operation are null. CloudWatch does not perform unit conversions.

implementation of the callback methods in this interface to receive notification of successful or

AmazonCloudWatchAsyncGets 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.
Percentile statistics are not available for metrics when any of the metric values are negative numbers.

AmazonCloudWatchAsyncCreates or updates a composite alarm. When you create a composite alarm, you specify a rule expression for the alarm that takes into account the alarm states of other alarms that you have created. The composite alarm goes into ALARM state only if all conditions of the rule are met.
The alarms specified in a composite alarm's rule expression can include metric alarms and other composite alarms.
Using composite alarms can reduce alarm noise. You can create multiple metric alarms, and also create a composite alarm and set up alerts only for the composite alarm. For example, you could create a composite alarm that goes into ALARM state only when more than one of the underlying metric alarms are in ALARM state.
Currently, the only alarm actions that can be taken by composite alarms are notifying SNS topics.
It is possible to create a loop or cycle of composite alarms, where composite alarm A depends on composite alarm B, and composite alarm B also depends on composite alarm A. In this scenario, you can't delete any composite alarm that is part of the cycle because there is always still a composite alarm that depends on that alarm that you want to delete.
To get out of such a situation, you must break the cycle by changing the rule of one of the composite alarms in
the cycle to remove a dependency that creates the cycle. The simplest change to make to break a cycle is to
change the AlarmRule of one of the alarms to False.
Additionally, the evaluation of composite alarms stops if CloudWatch detects a cycle in the evaluation path.
When this operation creates an alarm, the alarm state is immediately set to INSUFFICIENT_DATA. The
alarm is then evaluated and its state is set appropriately. Any actions associated with the new state are then
executed. For a composite alarm, this initial time after creation is the only time that the alarm can be in
INSUFFICIENT_DATA state.
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 iam:CreateServiceLinkedRole to create a composite alarm that
has Systems Manager OpsItem actions.

AmazonCloudWatchAsyncCreates 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.
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.

If you are an IAM user, you must have Amazon EC2 permissions for some alarm operations:
The iam:CreateServiceLinkedRole for all alarms with EC2 actions
The iam:CreateServiceLinkedRole to create an alarm with Systems Manager OpsItem actions.
The first time you create an alarm in the Management Console, the CLI, or by using the PutMetricAlarm API,
CloudWatch creates the necessary service-linked role for you. The service-linked roles are called
AWSServiceRoleForCloudWatchEvents and AWSServiceRoleForCloudWatchAlarms_ActionSSM. For
more information, see Amazon Web Services service-linked role.
Cross-account alarms
You can set an alarm on metrics in the current account, or in another account. To create a cross-account alarm that watches a metric in a different account, you must have completed the following pre-requisites:
The account where the metrics are located (the sharing account) must already have a sharing role named CloudWatch-CrossAccountSharingRole. If it does not already have this role, you must create it using the instructions in Set up a sharing account in Cross-account cross-Region CloudWatch console. The policy for that role must grant access to the ID of the account where you are creating the alarm.
The account where you are creating the alarm (the monitoring account) must already have a service-linked role named AWSServiceRoleForCloudWatchCrossAccount to allow CloudWatch to assume the sharing role in the sharing account. If it does not, you must create it following the directions in Set up a monitoring account in Cross-account cross-Region CloudWatch console.

AmazonCloudWatchAsyncPublishes 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.
You can publish either individual data points in the Value field, or arrays of values and the number
of times each value occurred during the period by using the Values and Counts fields in
the MetricDatum structure. Using the Values and Counts method enables you
to publish up to 150 values per metric with one PutMetricData request, and supports retrieving
percentile statistics on this data.
Each PutMetricData request is limited to 40 KB in size for HTTP POST requests. You can send a
payload compressed by gzip. Each request is also limited to no more than 20 different metrics.
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 -2^360 to 2^360. 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. Each dimension consists of a Name and Value pair. For more information about specifying dimensions, see Publishing Metrics in the Amazon CloudWatch User Guide.
You specify the time stamp to be associated with each data point. You can specify time stamps that are as much as two weeks before the current date, and as much as 2 hours after the current day and time.
Data points with time stamps from 24 hours ago or longer can take at least 48 hours to become available for GetMetricData or GetMetricStatistics from the time they are submitted. Data points with time stamps between 3 and 24 hours ago can take as much as 2 hours to become available for for GetMetricData or GetMetricStatistics.
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 and Min, Max, and
Sum are all equal.
The Min and Max are equal, and Sum is equal to Min multiplied
by SampleCount.

sends an SNS message.
Metric alarms returns to their actual state quickly, often within seconds. Because the metric alarm state change happens quickly, it is typically only visible in the alarm's History tab in the Amazon CloudWatch console or through DescribeAlarmHistory.
If you use SetAlarmState on a composite alarm, the composite alarm is not guaranteed to return to
its actual state. It returns to its actual state only once any of its children alarms change state. It is also
reevaluated if you update its configuration.
If an alarm triggers EC2 Auto Scaling policies or application Auto Scaling policies, you must include information
