Exemplar class
A representation of an exemplar, which is a sample input measurement. Exemplars also hold information about the environment when the measurement was recorded, for example the span and trace ID of the active span when the exemplar was recorded.

Properties
- asDouble ↔ double
-
getter/setter pair
- asInt ↔ Int64
-
getter/setter pair
- eventPlugin → EventPlugin?
-
Subclasses can override this getter to be notified of changes
to protobuf fields.
no setterinherited
-
filteredAttributes
→ List<
KeyValue> -
The set of key/value pairs that were filtered out by the aggregator, but
recorded alongside the original measurement. Only key/value pairs that were
filtered out by the aggregator should be included
no setter
- hashCode → int
-
Calculates a hash code based on the contents of the protobuf.
no setterinherited
- info_ → BuilderInfo
-
no setteroverride
- isFrozen → bool
-
Returns
trueif this message is marked read-only. Otherwisefalse.no setterinherited - runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
-
spanId
↔ List<
int> -
(Optional) Span ID of the exemplar trace.
span_id may be missing if the measurement is not recorded inside a trace
or if the trace is not sampled.
getter/setter pair
- timeUnixNano ↔ Int64
-
time_unix_nano is the exact time when this exemplar was recorded
getter/setter pair
-
traceId
↔ List<
int> -
(Optional) Trace ID of the exemplar trace.
trace_id may be missing if the measurement is not recorded inside a trace
or if the trace is not sampled.
