                                     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.

        `putMetricAlarm` インタフェース内 `AmazonCloudWatch`
      パラメータ:

        `LimitExceededException`
        `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.

                                    AmazonClientException

      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.

                                               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.

      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.

    - #### getMetricStatistics

          public GetMetricStatisticsResult getMetricStatistics(GetMetricStatisticsRequest getMetricStatisticsRequest)

      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

        `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.

      Retrieves history for the specified alarm. Filter alarms by date range or item type. If an alarm name is not specified, Amazon CloudWatch returns histories for all of the owner's alarms.

      NOTE: Amazon CloudWatch retains the history of an alarm for two weeks, whether or not you delete the alarm.

    - #### setEndpoint

          public void setEndpoint(java.lang.String endpoint,
                         java.lang.String serviceName,
                         java.lang.String regionId)
                           throws java.lang.IllegalArgumentException

      Overrides the default endpoint for this client ("https://monitoring.amazonaws.com") and explicitly provides an AWS region ID and AWS service name to use when the client calculates a signature for requests. In almost all cases, this region ID and service name are automatically determined from the endpoint, and callers should use the simpler one-argument form of setEndpoint instead of this method.

      This method is not threadsafe. Endpoints should be configured when the client is created and before any service requests are made. Changing it afterwards creates inevitable race conditions for any service requests in transit.

      Callers can pass in just the endpoint (ex: "monitoring.amazonaws.com") or a full URL, including the protocol (ex: "https://monitoring.amazonaws.com"). If the protocol is not specified here, the default protocol from this client's `ClientConfiguration` will be used, which by default is HTTPS.

      パラメータ:
        `endpoint` - The endpoint (ex: "monitoring.amazonaws.com") or a full URL, including the protocol (ex: "https://monitoring.amazonaws.com") of the region specific AWS endpoint this client will communicate with.
        `serviceName` - The name of the AWS service to use when signing requests.
        `regionId` - The ID of the region in which this service resides.
      例外:
        `java.lang.IllegalArgumentException` - If any problems are detected with the specified endpoint.

    - #### getCachedResponseMetadata

          public ResponseMetadata getCachedResponseMetadata(AmazonWebServiceRequest request)

      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.

      定義:
        `getCachedResponseMetadata` インタフェース内 `AmazonCloudWatch`
      パラメータ:
        `request` - The originally executed request
      戻り値:
        The response metadata for the specified request, or null if none is available.
