getMetricStatisticsAsync
public Future<GetMetricStatisticsResult> getMetricStatisticsAsync(GetMetricStatisticsRequest request)
Description copied from interface:AmazonCloudWatchAsync
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. 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
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.

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 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 itsStateValue
is set appropriately. Any actions associated with theStateValue
is then executed.When updating an existing alarm, its StateValue
is left unchanged.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
andec2: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
, andec2: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 the ListMetrics action.
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 typeDouble
, 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

setAlarmStateAsync
public Future<SetAlarmStateResult> setAlarmStateAsync(SetAlarmStateRequest request)
Description copied from interface: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 throughDescribeAlarmHistory
