      # Describes how to combine multiple time series to provide a different view of
      # the data. Aggregation of time series is done in two steps. First, each time
      # series in the set is aligned to the same time interval boundaries, then the
      # set of time series is optionally reduced in number.Alignment consists of
      # applying the per_series_aligner operation to each time series after its data
      # has been divided into regular alignment_period time intervals. This process
      # takes all of the data points in an alignment period, applies a mathematical
      # transformation such as averaging, minimum, maximum, delta, etc., and converts
      # them into a single data point per period.Reduction is when the aligned and
      # transformed time series can optionally be combined, reducing the number of
      # time series through similar mathematical transformations. Reduction involves
      # applying a cross_series_reducer to all the time series, optionally sorting the
      # time series into subsets with group_by_fields, and applying the reducer to
      # each subset.The raw time series data can contain a huge amount of information
      # from multiple sources. Alignment and reduction transforms this mass of data
      # into a more manageable and representative collection of data, for example "the
      # 95% latency across the average of all tasks in a cluster". This representative
      # data can be more easily graphed and comprehended, and the individual time
      # series data is still available for later drilldown. For more details, see

        # Annotation ] | Annotation | "1" ; Annotation = "`" NAME "`" ; Notes:
        # Annotation is just a comment if it follows a UNIT. If the annotation is used
        # alone, then the unit is equivalent to 1. For examples, `request`/s == 1/s, By`
        # transmitted`/s == By/s. NAME is a sequence of non-blank printable ASCII
        # characters not containing ` or `. 1 represents a unitary dimensionless unit (
        # https://en.wikipedia.org/wiki/Dimensionless_quantity) of 1, such as in 1/s. It
        # is typically used when none of the basic units are appropriate. For example, "
        # new users per day" can be represented as 1/d or `new-users`/d (and a metric
        # value 5 would mean "5 new users). Alternatively, "thousands of page views per
        # day" would be represented as 1000/d or k1/d or k`page_views`/d (and a metric
        # value of 5.3 would mean "5300 page views per day"). % represents dimensionless
        # value of 1/100, and annotates values giving a percentage (so the metric values
        # are typically in the range of 0..100, and a metric value 3 means "3 percent").
