OpenTelemetry Protocol Buffer definitions for Dart

This file exports all the generated protobuf classes for OpenTelemetry.

Classes

AggregationTemporality
AggregationTemporality defines how a metric aggregator reports aggregated values. It describes how those values relate to the time interval over which they are aggregated.
AnyValue
AnyValue is used to represent any type of attribute value. AnyValue may contain a primitive value such as a string or integer or it may contain an arbitrary nested object containing arrays, key-value lists and primitives.
ArrayValue
ArrayValue is a list of AnyValue messages. We need ArrayValue as a message since oneof in AnyValue does not allow repeated fields.
DataPointFlags
DataPointFlags is defined as a protobuf 'uint32' type and is to be used as a bit-field representing 32 distinct boolean flags. Each flag defined in this enum is a bit-mask. To test the presence of a single flag in the flags of a data point, for example, use an expression like:
Exemplar
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.
ExponentialHistogram
ExponentialHistogram represents the type of a metric that is calculated by aggregating as a ExponentialHistogram of all reported double measurements over a time interval.
ExponentialHistogramDataPoint
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.
ExponentialHistogramDataPoint_Buckets
Buckets are a set of bucket counts, encoded in a contiguous array of counts.
ExportLogsPartialSuccess
ExportLogsServiceRequest
ExportLogsServiceResponse
ExportMetricsPartialSuccess
ExportMetricsServiceRequest
ExportMetricsServiceResponse
ExportTracePartialSuccess
ExportTraceServiceRequest
ExportTraceServiceResponse
Gauge
Gauge represents the type of a scalar metric that always exports the "current value" for every data point. It should be used for an "unknown" aggregation.
Histogram
Histogram represents the type of a metric that is calculated by aggregating as a Histogram of all reported measurements over a time interval.
HistogramDataPoint
HistogramDataPoint is a single data point in a timeseries that describes the time-varying values of a Histogram. A Histogram contains summary statistics for a population of values, it may optionally contain the distribution of those values across a set of buckets.
InstrumentationScope
InstrumentationScope is a message representing the instrumentation scope information such as the fully qualified name and version.
KeyValue
KeyValue is a key-value pair that is used to store Span attributes, Link attributes, etc.
KeyValueList
KeyValueList is a list of KeyValue messages. We need KeyValueList as a message since oneof in AnyValue does not allow repeated fields. Everywhere else where we need a list of KeyValue messages (e.g. in Span) we use repeated KeyValue directly to avoid unnecessary extra wrapping (which slows down the protocol). The 2 approaches are semantically equivalent.
LogRecord
A log record according to OpenTelemetry Log Data Model: https://github.com/open-telemetry/oteps/blob/main/text/logs/0097-log-data-model.md
LogRecordFlags
LogRecordFlags represents constants used to interpret the LogRecord.flags field, which is protobuf 'fixed32' type and is to be used as bit-fields. Each non-zero value defined in this enum is a bit-mask. To extract the bit-field, for example, use an expression like:
LogsData
LogsData represents the logs data that can be stored in a persistent storage, OR can be embedded by other protocols that transfer OTLP logs data but do not implement the OTLP protocol.
LogsServiceBase
LogsServiceClient
Service that can be used to push logs between one Application instrumented with OpenTelemetry and an collector, or between an collector and a central collector (in this case logs are sent/received to/from multiple Applications).
Metric
Defines a Metric which has one or more timeseries. The following is a brief summary of the Metric data model. For more details, see:
MetricsData
MetricsData represents the metrics data that can be stored in a persistent storage, OR can be embedded by other protocols that transfer OTLP metrics data but do not implement the OTLP protocol.
MetricsServiceBase
MetricsServiceClient
Service that can be used to push metrics between one Application instrumented with OpenTelemetry and a collector, or between a collector and a central collector.
NumberDataPoint
NumberDataPoint is a single data point in a timeseries that describes the time-varying scalar value of a metric.
Resource
Resource information.
ResourceLogs
A collection of ScopeLogs from a Resource.
ResourceMetrics
A collection of ScopeMetrics from a Resource.
ResourceSpans
A collection of ScopeSpans from a Resource.
ScopeLogs
A collection of Logs produced by a Scope.
ScopeMetrics
A collection of Metrics produced by an Scope.
ScopeSpans
A collection of Spans produced by an InstrumentationScope.
SeverityNumber
Possible values for LogRecord.SeverityNumber.
Span
A Span represents a single operation performed by a single component of the system.
Span_Event
Event is a time-stamped annotation of the span, consisting of user-supplied text description and key-value pairs.
A pointer from the current span to another span in the same trace or in a different trace. For example, this can be used in batching operations, where a single batch handler processes multiple requests from different traces or when the handler receives a request from a different project.
Span_SpanKind
SpanKind is the type of span. Can be used to specify additional relationships between spans in addition to a parent/child relationship.
SpanFlags
SpanFlags represents constants used to interpret the Span.flags field, which is protobuf 'fixed32' type and is to be used as bit-fields. Each non-zero value defined in this enum is a bit-mask. To extract the bit-field, for example, use an expression like:
Status
The Status type defines a logical error model that is suitable for different programming environments, including REST APIs and RPC APIs.
Status_StatusCode
For the semantics of status codes see https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/trace/api.md#set-status
Sum
Sum represents the type of a scalar metric that is calculated as a sum of all reported measurements over a time interval.
Summary
Summary metric data are used to convey quantile summaries, a Prometheus (see: https://prometheus.io/docs/concepts/metric_types/#summary) and OpenMetrics (see: https://github.com/OpenObservability/OpenMetrics/blob/4dbf6075567ab43296eed941037c12951faafb92/protos/prometheus.proto#L45) data type. These data points cannot always be merged in a meaningful way. While they can be useful in some applications, histogram data points are recommended for new applications.
SummaryDataPoint
SummaryDataPoint is a single data point in a timeseries that describes the time-varying values of a Summary metric.
SummaryDataPoint_ValueAtQuantile
Represents the value at a given quantile of a distribution.
TracesData
TracesData represents the traces data that can be stored in a persistent storage, OR can be embedded by other protocols that transfer OTLP traces data but do not implement the OTLP protocol.
TraceServiceBase
TraceServiceClient
Service that can be used to push spans between one Application instrumented with OpenTelemetry and a collector, or between a collector and a central collector (in this case spans are sent/received to/from multiple Applications).
