Overview

Distribution contains summary statistics for a population of values and, optionally, a histogram representing the distribution of those values across a specified set of histogram buckets.The summary statistics are the count, mean, sum of the squared deviation from the mean, the minimum, and the maximum of the set of population of values.The histogram is based on a sequence of buckets and gives a count of values that fall into each bucket. The boundaries of the buckets are given either explicitly or by specifying parameters for a method of computing them (buckets of fixed width or buckets of exponentially increasing width).Although it is not forbidden, it is generally a bad idea to include non-finite values (infinities or NaNs) in the population of values, as this will render the mean and sum_of_squared_deviation fields meaningless.

#bucket_counts ⇒ Array<String>

If bucket_options is given, then the sum of the values in bucket_counts must equal the value in count. If bucket_options is not given, no bucket_counts fields may be given.Bucket counts are given in order under the numbering scheme described above (the underflow bucket has number 0; the finite buckets, if any, have numbers 1 through N-2; the overflow bucket has number N-1).The size of bucket_counts must be no greater than N as defined in bucket_options. Any suffix of trailing zero bucket_count fields may be omitted. Corresponds to the JSON property bucketCounts

Returns:

  • (Array<String>)

#bucket_options ⇒ Google::Apis::MonitoringV3::BucketOptions

A Distribution may optionally contain a histogram of the values in the population. The histogram is given in bucket_counts as counts of values that fall into one of a sequence of non-overlapping buckets. The sequence of buckets is described by bucket_options.A bucket specifies an inclusive lower bound and exclusive upper bound for the values that are counted for that bucket. The upper bound of a bucket is strictly greater than the lower bound. The sequence of N buckets for a Distribution consists of an underflow bucket ( number 0), zero or more finite buckets (number 1 through N - 2) and an overflow bucket (number N - 1). The buckets are contiguous: the lower bound of bucket i (i > 0) is the same as the upper bound of bucket i - 1. The buckets span the whole range of finite values: lower bound of the underflow bucket is - infinity and the upper bound of the overflow bucket is +infinity. The finite buckets are so-called because both bounds are finite.BucketOptions describes bucket boundaries in one of three ways. Two describe the boundaries by giving parameters for a formula to generate boundaries and one gives the bucket boundaries explicitly.If bucket_options is not given, then no bucket_counts may be given. Corresponds to the JSON property bucketOptions

#count ⇒ String

The number of values in the population. Must be non-negative. Corresponds to the JSON property count

#mean ⇒ Float

The arithmetic mean of the values in the population. If count is zero then this field must be zero. Corresponds to the JSON property mean

#sum_of_squared_deviation ⇒ Float

The sum of squared deviations from the mean of the values in the population. For values x_i this is: Sumi=1..n Knuth, "The Art of Computer Programming", Vol. 2, page 323, 3rd edition describes Welford's method for accumulating this sum in one pass.If count is zero then this field must be zero. Corresponds to the JSON property sumOfSquaredDeviation

Returns:

  • (Float)
