public final class Distribution extends GeneratedMessageV3 implements DistributionOrBuilder
Distribution contains summary statistics for a population of values. It
optionally contains a histogram representing the distribution of those values
across a set of 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 formulas for buckets of fixed or exponentially increasing
widths.
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.

getBucketCounts(int index)
public long getBucketCounts(int index)
The number of values in each bucket of the histogram, as described in
bucket_options. If the distribution does not have a histogram, then omit
this field. If there is a histogram, then the sum of the values in
bucket_counts must equal the value in the count field of the
distribution.
If present, bucket_counts should contain N values, where N is the number
of buckets specified in bucket_options. If you supply fewer than N
values, the remaining values are assumed to be 0.
The order of the values in bucket_counts follows the bucket numbering
schemes described for the three bucket types. The first value must be the
count for the underflow bucket (number 0). The next N-2 values are the
counts for the finite buckets (number 1 through N-2). The N'th value in
bucket_counts is the count for the overflow bucket (number N-1).

| Name | Description |
| index | int
The index of the element to return.

Returns
| Type | Description |
| long | The bucketCounts at the given index.
