EndTime *time.Time

//
// - Requests - The total number of viewer requests received by your Lightsail
// distribution, for all HTTP methods, and for both HTTP and HTTPS requests.
//
// Statistics : The most useful statistic is Sum .
//
// Unit : The published unit is None .
//
// - BytesDownloaded - The number of bytes downloaded by viewers for GET, HEAD,
// and OPTIONS requests.
//
// Statistics : The most useful statistic is Sum .
//
// Unit : The published unit is None .
//
// - BytesUploaded - The number of bytes uploaded to your origin by your
// Lightsail distribution, using POST and PUT requests.
//
// Statistics : The most useful statistic is Sum .
//
// Unit : The published unit is None .
//
// - TotalErrorRate - The percentage of all viewer requests for which the
// response's HTTP status code was 4xx or 5xx.
//
// Statistics : The most useful statistic is Average .
//
// Unit : The published unit is Percent .
//
// - 4xxErrorRate - The percentage of all viewer requests for which the
// response's HTTP status cod was 4xx. In these cases, the client or client viewer
// may have made an error. For example, a status code of 404 (Not Found) means that
// the client requested an object that could not be found.
//
// Statistics : The most useful statistic is Average .
//
// Unit : The published unit is Percent .
//
// - 5xxErrorRate - The percentage of all viewer requests for which the
// response's HTTP status code was 5xx. In these cases, the origin server did not
// satisfy the requests. For example, a status code of 503 (Service Unavailable)
// means that the origin server is currently unavailable.

Period *int32

// The following statistics are available:
//
// - Minimum - The lowest value observed during the specified period. Use this

//
// - Maximum - The highest value observed during the specified period. Use this
// value to determine high volumes of activity for your application.
//
// - Sum - All values submitted for the matching metric added together. You can
// use this statistic to determine the total volume of a metric.
//
// - Average - The value of Sum / SampleCount during the specified period. By
// comparing this statistic with the Minimum and Maximum values, you can determine
// the full scope of a metric and how close the average use is to the Minimum and
// Maximum values. This comparison helps you to know when to increase or decrease
// your resources.
//
// - SampleCount - The count, or number, of data points used for the statistical
// calculation.
//
