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 service method on AmazonCloudWatch.
Throws:
com.amazonaws.services.cloudwatch.model.LimitExceededException
com.amazonaws.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.
com.amazonaws.AmazonServiceException If an error response is returned by AmazonCloudWatch indicating either a problem with the data in the request, or a server side issue.

        Request<PutMetricAlarmRequestrequest = null;
        awsRequestMetrics.startEvent(.);
        
        try {
            awsRequestMetrics.startEvent(.);
            try {
                request = new PutMetricAlarmRequestMarshaller().marshall(super.beforeMarshalling(putMetricAlarmRequest));
                // Binds the request metrics to the current request.
                request.setAWSRequestMetrics(awsRequestMetrics);
            } finally {

        } finally {
            
            endClientExecution(awsRequestMetricsrequestnull);
        }
    }
    
    

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.

NOTE: If you create a metric with the PutMetricData action, allow up to fifteen minutes for the metric to appear in calls to the ListMetrics action.

The size of a PutMetricData request is limited to 8 KB for HTTP GET requests and 40 KB for HTTP POST requests.

IMPORTANT: Although the Value parameter accepts numbers of type Double, Amazon CloudWatch truncates values with very large exponents. Values with base-10 exponents greater than 126 (1 x 10^126) are truncated. Likewise, values with base-10 exponents less than -130 (1 x 10^-130) are also truncated.

Parameters:
putMetricDataRequest Container for the necessary parameters to execute the PutMetricData service method on AmazonCloudWatch.
Throws:
com.amazonaws.services.cloudwatch.model.InvalidParameterValueException
com.amazonaws.services.cloudwatch.model.InternalServiceException
com.amazonaws.services.cloudwatch.model.InvalidParameterCombinationException
com.amazonaws.services.cloudwatch.model.MissingRequiredParameterException
com.amazonaws.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.
com.amazonaws.AmazonServiceException If an error response is returned by AmazonCloudWatch indicating either a problem with the data in the request, or a server side issue.

        }
    }
    
    

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.

NOTE: If you create a metric with the PutMetricData action, allow up to fifteen minutes for the metric to appear in calls to the ListMetrics action.

Parameters:
listMetricsRequest Container for the necessary parameters to execute the ListMetrics service method on AmazonCloudWatch.
Returns:
The response from the ListMetrics service method, as returned by AmazonCloudWatch.
Throws:
com.amazonaws.services.cloudwatch.model.InternalServiceException
com.amazonaws.services.cloudwatch.model.InvalidParameterValueException
com.amazonaws.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.
com.amazonaws.AmazonServiceException If an error response is returned by AmazonCloudWatch indicating either a problem with the data in the request, or a server side issue.

        } finally {
            
            endClientExecution(awsRequestMetricsrequestresponse);
        }
    }
    
    

Gets statistics for the specified metric.

NOTE: The maximum number of data points returned from a single GetMetricStatistics request is 1,440. If a request is made that generates more than 1,440 data points, 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.

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.

NOTE: The maximum number of data points that can be queried is 50,850; whereas the maximum number of data points returned is 1,440.

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

Parameters:
getMetricStatisticsRequest Container for the necessary parameters to execute the GetMetricStatistics service method on AmazonCloudWatch.

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

Returns additional metadata for a previously executed successful, request, typically used for debugging issues where a service isn't acting as expected. This data isn't considered part of the result data returned by an operation, so it's available through this separate, diagnostic interface.

Response metadata is only cached for a limited period of time, so if you need to access this extra diagnostic information for an executed request, you should use this method to retrieve it as soon as possible after executing the request.

Parameters:
request The originally executed request
Returns:
The response metadata for the specified request, or null if none is available.
        return .getResponseMetadataForRequest(request);
