ExponentialHistogramDataPoint class

ExponentialHistogramDataPoint is a single data point in a timeseries that describes the time-varying values of a ExponentialHistogram of double values. A ExponentialHistogram contains summary statistics for a population of values, it may optionally contain the distribution of those values across a set of buckets.

Properties

attributes → List<KeyValue>
The set of key/value pairs that uniquely identify the timeseries from where this point belongs. The list may be empty (may contain 0 elements). Attribute keys MUST be unique (it is not allowed to have more than one attribute with the same key).
no setter
count ↔ Int64
count is the number of values in the population. Must be non-negative. This value must be equal to the sum of the "bucket_counts" values in the positive and negative Buckets plus the "zero_count" field.
getter/setter pair
eventPlugin → EventPlugin?
Subclasses can override this getter to be notified of changes to protobuf fields.
no setterinherited
exemplars → List<Exemplar>
(Optional) List of exemplars collected from measurements that were used to form the data point
no setter
flags ↔ int
Flags that apply to this specific data point. See DataPointFlags for the available flags and their meaning.
getter/setter pair
hashCode → int
Calculates a hash code based on the contents of the protobuf.
no setterinherited
info_ → BuilderInfo
no setteroverride
isFrozen → bool
Returns true if this message is marked read-only. Otherwise false.
no setterinherited
max ↔ double
max is the maximum value over (start_time, end_time].
getter/setter pair
min ↔ double
min is the minimum value over (start_time, end_time].
getter/setter pair
negative ↔ ExponentialHistogramDataPoint_Buckets
negative carries the negative range of exponential bucket counts.
getter/setter pair
positive ↔ ExponentialHistogramDataPoint_Buckets
positive carries the positive range of exponential bucket counts.
getter/setter pair
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
scale ↔ int
scale describes the resolution of the histogram. Boundaries are located at powers of the base, where:
getter/setter pair
startTimeUnixNano ↔ Int64
StartTimeUnixNano is optional but strongly encouraged, see the the detailed comments above Metric.
getter/setter pair
sum ↔ double
sum of the values in the population. If count is zero then this field must be zero.
getter/setter pair
timeUnixNano ↔ Int64
TimeUnixNano is required, see the detailed comments above Metric.
getter/setter pair
unknownFields → UnknownFieldSet
no setterinherited
zeroCount ↔ Int64
zero_count is the count of values that are either exactly zero or within the region considered zero by the instrumentation at the tolerated degree of precision. This bucket stores values that cannot be expressed using the standard exponential formula as well as values that have been rounded to zero.
getter/setter pair
zeroThreshold ↔ double
ZeroThreshold may be optionally set to convey the width of the zero region. Where the zero region is defined as the closed interval -ZeroThreshold, ZeroThreshold. When ZeroThreshold is 0, zero count bucket stores values that cannot be expressed using the standard exponential formula as well as values that have been rounded to zero.
