Abstract types
BucketOptions
BucketOptions
describes the bucket boundaries used to create a histogram for the distribution. The buckets can be in a linear sequence, an exponential sequence, or each bucket can be specified explicitly.
BucketOptions
does not include the number of values in each bucket.
A bucket has an inclusive lower bound and exclusive upper bound for the values that are counted for that bucket. The upper bound of a bucket must be 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 socalled because both bounds are finite.
Properties
Parameter 


linearBuckets 
Object The linear bucket. This object should have the same structure as Linear 
exponentialBuckets 
Object The exponential buckets. This object should have the same structure as Exponential 
explicitBuckets 
Object The explicit buckets. This object should have the same structure as Explicit 
Distribution
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 nonfinite values (infinities or NaNs) in the population of values, as this will render the mean
and sum_of_squared_deviation
fields meaningless.
Properties
Parameter 


count 
number The number of values in the population. Must be nonnegative. This value must equal the sum of the values in 
mean 
number The arithmetic mean of the values in the population. If 
sumOfSquaredDeviation

Exemplar
Exemplars are example points that may be used to annotate aggregated distribution values. They are metadata that gives information about a particular value added to a Distribution bucket, such as a trace ID that was active when a value was added. They may contain further information, such as a example values and timestamps, origin, etc.

There are size(bounds) + 1
(= N) buckets. Bucket i
has the following boundaries:
Upper bound (0 <= i < N1): bounds[i] Lower bound (1 <= i < N); bounds[i  1]
The bounds
field must contain at least one element. If bounds
has only one element, then there are no finite buckets, and that single element is the common boundary of the overflow and underflow buckets.
Property

MonitoredResource
An object representing a resource that can be used for monitoring, logging, billing, or other purposes. Examples include virtual machine instances, databases, and storage devices such as disks. The type
field identifies a
MonitoredResourceDescriptor object that describes the resource's schema. Information in the labels
field identifies the actual resource and its attributes according to the schema. For example, a particular Compute Engine
VM instance could be represented by the following object, because the MonitoredResourceDescriptor for
"gce_instance"
has labels
"instance_id"
and "zone"
:
{ "type": "gce_instance",
"labels": { "instance_id": "12345678901234",
"zone": "uscentral1a" }}

string Required. The monitored resource type. This field must match the 
labels 
Object with string properties Required. Values for all of the labels listed in the associated monitored resource descriptor. For example, Compute Engine VM instances use the labels 
MonitoredResourceDescriptor
An object that describes the schema of a MonitoredResource object using a type name and a set of labels. For example, the monitored resource descriptor for Google Compute Engine VM instances has a type of
"gce_instance"

"zone"
