Class Distribution (1.0.3)

Distribution(mapping=None, *, ignore_unknown_fields=False, **kwargs)

Distribution represents a frequency distribution of double- alued sample points. It contains the size of the population of sample points plus additional optional information:

  • the arithmetic mean of the samples
  • the minimum and maximum of the samples
  • the sum-squared-deviation of the samples, used to compute variance
  • a histogram of the values of the sample points

Attributes

NameDescription
count int
The total number of samples in the distribution. Must be >= 0.
mean float
The arithmetic mean of the samples in the distribution. If count is zero then this field must be zero.
minimum float
The minimum of the population of values. Ignored if count is zero.
maximum float
The maximum of the population of values. Ignored if count is zero.
sum_of_squared_deviation float
The sum of squared deviations from the mean: Sum[i=1..count]((x_i - mean)^2) where each x_i is a sample values. If count is zero then this field must be zero, otherwise validation of the request fails.
bucket_counts Sequence[int]
The number of samples in each histogram bucket. bucket_counts are optional. If present, they must sum to the count value. The buckets are defined below in bucket_option. There are N buckets. bucket_counts[0] is the number of samples in the underflow bucket. bucket_counts[1] to bucket_counts[N-1] are the numbers of samples in each of the finite buckets. And bucket_counts[N] is the number of samples in the overflow bucket. See the comments of\ bucket_option\` below for more details. Any suffix of trailing zeros may be omitted.
linear_buckets google.cloud.servicecontrol_v1.types.Distribution.LinearBuckets
Buckets with constant width.
exponential_buckets google.cloud.servicecontrol_v1.types.Distribution.ExponentialBuckets
Buckets with exponentially growing width.
explicit_buckets google.cloud.servicecontrol_v1.types.Distribution.ExplicitBuckets
Buckets with arbitrary user-provided width.
exemplars Sequence[google.api.distribution_pb2.Exemplar]
Example points. Must be in increasing order of value field.

Classes

ExplicitBuckets

ExplicitBuckets(mapping=None, *, ignore_unknown_fields=False, **kwargs)

Describing buckets with arbitrary user-provided width. .. attribute:: bounds

'bound' is a list of strictly increasing boundaries between buckets. Note that a list of length N-1 defines N buckets because of fenceposting. See comments on bucket_options for details.

The i'th finite bucket covers the interval [bound[i-1], bound[i]) where i ranges from 1 to bound_size() - 1. Note that there are no finite buckets at all if 'bound' only contains a single element; in that special case the single bound defines the boundary between the underflow and overflow buckets.

ExponentialBuckets

ExponentialBuckets(mapping=None, *, ignore_unknown_fields=False, **kwargs)

Describing buckets with exponentially growing width. .. attribute:: num_finite_buckets

The number of finite buckets. With the underflow and overflow buckets, the total number of buckets is num_finite_buckets + 2. See comments on bucket_options for details.

:type: int

LinearBuckets

LinearBuckets(mapping=None, *, ignore_unknown_fields=False, **kwargs)

Describing buckets with constant width. .. attribute:: num_finite_buckets

The number of finite buckets. With the underflow and overflow buckets, the total number of buckets is num_finite_buckets + 2. See comments on bucket_options for details.
