  • All Implemented Interfaces:
    java.util.concurrent.Callable<com.amazonaws.services.cloudwatch.model.GetMetricStatisticsResult>
    public class GetMetricStatisticsTask
extends java.lang.Object
implements java.util.concurrent.Callable<com.amazonaws.services.cloudwatch.model.GetMetricStatisticsResult>
    A Callable task that, when executed, requests statistics for a particular metric to be fetched from AWS CloudWatch in a given region.

    The returned GetMetricStatisticsResponse object stores the query metric in its label field and will store the list of Datapoints sorted in increasing order of time stamp (oldest first).

        Constructs a new GetMetricStatisticsTask request.
        Parameters:
        awsAccessKeyId - AWS access key id for the account to be used.
        awsSecretAccessKey - AWS secret access key for the account to be used.
        region - The AWS region that the request will be sent to.
        namespace - The Amazon CloudWatch namespace of the metric to fetch.
        metric - The CloudWatch metric that to retrieve data points for.
        period - The granularity of returned metric values (in seconds). The statistics function will aggregate metric values with this level of granularity. Must be at least 60 seconds and must be a multiple of 60.
        dimensions - The dimensions (key-value pairs) used to narrow down the result set. Only data points matching the specified dimensions will be returned.
        queryInterval - The time interval for the query. Only Datapoints whose time stamp lies within this interval will be returned. May be null.
        statistic - The aggregation method(s) to apply to metric values. Can be any of "Sum", "Average", "Minimum", "Maximum" and "SampleCount". The returned Datapoints will contain one value for each specified statistic.
