All Known Implementing Classes:

public interface AmazonCloudWatchAsync
extends AmazonCloudWatch

Interface for accessing AmazonCloudWatch asynchronously, using Java Futures.

Amazon CloudWatch is a web service that enables you to monitor and manage various metrics, as well as configure alarm actions based on data from metrics.

Amazon CloudWatch monitoring enables you to collect, analyze, and view system and application metrics so that you can make operational and business decisions more quickly and with greater confidence. You can use Amazon CloudWatch to collect metrics about your AWS resources, such as the performance of your Amazon EC2 instances.

If you are registered for an AWS product that supports Amazon CloudWatch, the service automatically pushes basic metrics to CloudWatch for you. Once Amazon CloudWatch contains metrics, you can calculate statistics based on that data.

Amazon CloudWatch alarms help you implement decisions more easily by enabling you do things like send notifications or automatically make changes to the resources you are monitoring, based on rules that you define. For example, you can create alarms that initiate Auto Scaling and Simple Notification Service actions on your behalf.

Method Detail

putMetricAlarmAsync

Future<Void> putMetricAlarmAsync(PutMetricAlarmRequest putMetricAlarmRequest)
                                 throws AmazonServiceException,
                                        AmazonClientException

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 its StateValue is set appropriately. Any actions associated with the StateValue is then executed.

NOTE: When updating an existing alarm, its StateValue is left unchanged.

Parameters:

putMetricAlarmRequest - Container for the necessary parameters to execute the PutMetricAlarm operation on AmazonCloudWatch.

Returns:

A Java Future object containing the response from the PutMetricAlarm service method, as returned by AmazonCloudWatch.

Throws:

AmazonClientException - If any internal errors are encountered inside the client while attempting to make the request or handle the response. For example if a network connection is not available.

AmazonServiceException - If an error response is returned by AmazonCloudWatch indicating either a problem with the data in the request, or a server side issue.

listMetricsAsync

Future<ListMetricsResult> listMetricsAsync(ListMetricsRequest listMetricsRequest)
                                           throws AmazonServiceException,
                                                  AmazonClientException

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.

NOTE: Up to 500 results are returned for any one call. To retrieve further results, use returned NextToken values with subsequent ListMetrics operations.

Parameters:

listMetricsRequest - Container for the necessary parameters to execute the ListMetrics operation on AmazonCloudWatch.

Returns:

A Java Future object containing the response from the ListMetrics service method, as returned by AmazonCloudWatch.

Throws:

AmazonClientException - If any internal errors are encountered inside the client while attempting to make the request or handle the response. For example if a network connection is not available.

AmazonServiceException - If an error response is returned by AmazonCloudWatch indicating either a problem with the data in the request, or a server side issue.

getMetricStatisticsAsync

Future<GetMetricStatisticsResult> getMetricStatisticsAsync(GetMetricStatisticsRequest getMetricStatisticsRequest)

                                                                  AmazonClientException

Gets statistics for the specified metric.

NOTE: The maximum number of datapoints returned from a single GetMetricStatistics request is 1,440. If a request is made that generates more than 1,440 datapoints, Amazon CloudWatch returns an error. In such a case, alter the request by narrowing the specified time range or increasing the specified period. Alternatively, make multiple requests across adjacent time ranges.

Parameters:

getMetricStatisticsRequest - Container for the necessary parameters to execute the GetMetricStatistics operation on AmazonCloudWatch.

Returns:

A Java Future object containing the response from the GetMetricStatistics service method, as returned by AmazonCloudWatch.

Throws:

AmazonClientException - If any internal errors are encountered inside the client while attempting to make the request or handle the response. For example if a network connection is not available.

AmazonServiceException - If an error response is returned by AmazonCloudWatch indicating either a problem with the data in the request, or a server side issue.
