MetricDatum
Encapsulates the information sent to either create a metric or add new values to be aggregated into an existing metric.
Contents
 Counts.member.N

Array of numbers that is used along with the
Values
array. Each number in theCount
array is the number of times the corresponding value in theValues
array occurred during the period.If you omit the
Counts
array, the default of 1 is used as the value for each count. If you include aCounts
array, it must include the same amount of values as theValues
array.Type: Array of doubles
Required: No
 Dimensions.member.N

The dimensions associated with the metric.
Type: Array of Dimension objects
Array Members: Maximum number of 10 items.
Required: No
 MetricName

The name of the metric.
Type: String
Length Constraints: Minimum length of 1. Maximum length of 255.
Required: Yes
 StatisticValues

The statistical values for the metric.
Type: StatisticSet object
Required: No
 StorageResolution

Valid values are 1 and 60. Setting this to 1 specifies this metric as a highresolution metric, so that CloudWatch stores the metric with subminute resolution down to one second. Setting this to 60 specifies this metric as a regularresolution metric, which CloudWatch stores at 1minute resolution. Currently, high resolution is available only for custom metrics. For more information about highresolution metrics, see HighResolution Metrics in the Amazon CloudWatch User Guide.
This field is optional, if you do not specify it the default of 60 is used.
Type: Integer
Valid Range: Minimum value of 1.
Required: No
 Timestamp

The time the metric data was received, expressed as the number of milliseconds since Jan 1, 1970 00:00:00 UTC.
Type: Timestamp
Required: No
 Unit

When you are using a
Put
operation, this defines what unit you want to use when storing the metric.In a
Get
operation, this displays the unit that is used for the metric.Type: String
Valid Values:
Seconds  Microseconds  Milliseconds  Bytes  Kilobytes  Megabytes  Gigabytes  Terabytes  Bits  Kilobits  Megabits  Gigabits  Terabits  Percent  Count  Bytes/Second  Kilobytes/Second  Megabytes/Second  Gigabytes/Second  Terabytes/Second  Bits/Second  Kilobits/Second  Megabits/Second  Gigabits/Second  Terabits/Second  Count/Second  None
Required: No
 Value

The value for the metric.
Although the parameter accepts numbers of type Double, CloudWatch rejects values that are either too small or too large. Values must be in the range of 8.515920e109 to 1.174271e+108 (Base 10) or 2e360 to 2e360 (Base 2). In addition, special values (for example, NaN, +Infinity, Infinity) are not supported.
Type: Double
Required: No
 Values.member.N

Array of numbers representing the values for the metric during the period. Each unique value is listed just once in this array, and the corresponding number in the
Counts
array specifies the number of times that value occurred during the period. You can include up to 150 unique values in eachPutMetricData
action that specifies aValues
array.Although the
Values
array accepts numbers of typeDouble
, CloudWatch rejects values that are either too small or too large. Values must be in the range of 8.515920e109 to 1.174271e+108 (Base 10) or 2e360 to 2e360 (Base 2). In addition, special values (for example, NaN, +Infinity, Infinity) are not supported.Type: Array of doubles
Required: No
