TargetTrackingMetricDataQuery

Gets and sets the property Expression.

The math expression to perform on the returned data, if this object is performing a math expression. This expression can use the Id of the other metrics to refer to those metrics, and can also use the Id of other expressions to use the result of those expressions.

Conditional: Within each TargetTrackingMetricDataQuery object, you must specify either Expression or MetricStat, but not both.

Gets and sets the property Id.

A short name that identifies the object's results in the response. This name must be unique among all TargetTrackingMetricDataQuery objects specified for a single scaling policy. If you are performing math expressions on this set of data, this name represents that data and can serve as a variable in the mathematical expression. The valid characters are letters, numbers, and underscores. The first character must be a lowercase letter.

Gets and sets the property Label.

A human-readable label for this metric or expression. This is especially useful if this is a math expression, so that you know what the value represents.

Gets and sets the property MetricStat.

Information about the metric data to return.

Conditional: Within each TargetTrackingMetricDataQuery object, you must specify either Expression or MetricStat, but not both.

Gets and sets the property ReturnData.

Indicates whether to return the timestamps and raw data values of this metric.

If you use any math expressions, specify true for this value for only the final math expression that the metric specification is based on. You must specify false for ReturnData for all the other metrics and expressions used in the metric specification.

If you are only retrieving metrics and not performing any math expressions, do not specify anything for ReturnData. This sets it to its default (true).
