OpenTelemetry OTLP Exporters opentelemetry.exporter.otlp.proto.http

This library allows to export tracing data to an OTLP collector.

Usage

The OTLP Span Exporter allows to export OpenTelemetry traces to the OTLP collector.

You can configure the exporter with the following environment variables:

from opentelemetry import trace
from opentelemetry.exporter.otlp.proto.http.trace_exporter import OTLPSpanExporter
from opentelemetry.sdk.resources import Resource
from opentelemetry.sdk.trace import TracerProvider
from opentelemetry.sdk.trace.export import BatchSpanProcessor

# Resource can be required for some backends, e.g. Jaeger
# If resource wouldn't be set - traces wouldn't appears in Jaeger
resource = Resource(attributes={
    "service.name": "service"
})

trace.set_tracer_provider(TracerProvider(resource=resource))
tracer = trace.get_tracer(__name__)

otlp_exporter = OTLPSpanExporter()

span_processor = BatchSpanProcessor(otlp_exporter)

trace.get_tracer_provider().add_span_processor(span_processor)

with tracer.start_as_current_span("foo"):
    print("Hello world!")

API

OTLP Span Exporter

class opentelemetry.exporter.otlp.proto.grpc.trace_exporter.OTLPSpanExporter(endpoint=None, insecure=None, credentials=None, headers=None, timeout=None, compression=None, channel_options=None)[source]

OTLP span exporter

Parameters:

endpoint (Optional[str]) – OpenTelemetry Collector receiver endpoint
insecure (Optional[bool]) – Connection type
credentials (Optional[ChannelCredentials]) – Credentials object for server authentication
headers (Union[Sequence[Tuple[str, str]], Dict[str, str], str, None]) – Headers to send when exporting
timeout (Optional[float]) – Backend request timeout in seconds
compression (Optional[Compression]) – gRPC compression method to use

export(spans)[source]

Exports a batch of telemetry data.

Return type:: SpanExportResult
Returns:: The result of the export

shutdown()[source]

Shuts down the exporter.

Called when the SDK is shut down.

Return type:: None

force_flush(timeout_millis=30000)[source]

Nothing is buffered in this exporter, so this method does nothing.

Return type:: bool

class opentelemetry.exporter.otlp.proto.grpc.metric_exporter.OTLPMetricExporter(endpoint=None, insecure=None, credentials=None, headers=None, timeout=None, compression=None, preferred_temporality=None, preferred_aggregation=None, max_export_batch_size=None, channel_options=None)[source]

OTLP metric exporter

Parameters:

endpoint (str | None) – Target URL to which the exporter is going to send metrics
max_export_batch_size (int | None) – Maximum number of data points to export in a single request. This is to deal with gRPC’s 4MB message size limit. If not set there is no limit to the number of data points in a request. If it is set and the number of data points exceeds the max, the request will be split.
