Class MetricDataQuery

    • Method Detail

      • id

        public final String id()

        A short name that identifies the object's results in the response. This name must be unique among all MetricDataQuery 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.

        Returns:

      • expression

        public final String 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 MetricDataQuery object, you must specify either Expression or MetricStat, but not both.

        Returns:
        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 MetricDataQuery object, you must specify either Expression or MetricStat, but not both.

      • metricStat

        public final MetricStat metricStat()

        Information about the metric data to return.

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

        Returns:
        Information about the metric data to return.

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

      • label

        public final String 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.

        Returns:
        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.
      • returnData

        public final Boolean 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).

        Returns:
        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).

      • hashCode

        public final int hashCode()
        Overrides:
        hashCode in class Object
      • equals

        public final boolean equals​(Object obj)
        Overrides:
        equals in class Object
      • toString

        public final String toString()
        Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.
        Overrides:
        toString in class Object
      • getValueForField

        public final <T> Optional<T> getValueForField​(String fieldName,
                                                      Class<T> clazz)
