opentelemetry-exporter-google-cloud 0.12b0

Google Cloud integrations for OpenTelemetry

This library provides support for:

• Exporting traces to Google Cloud Trace

• Exporting metrics to Google Cloud Monitoring

For resource detection and GCP trace context propagation, see opentelemetry-tools-google-cloud.

Installation

pip install opentelemetry-exporter-google-cloud

Usage

Traces

from opentelemetry import trace
from opentelemetry.exporter.cloud_trace import CloudTraceSpanExporter
from opentelemetry.sdk.trace import TracerProvider
from opentelemetry.sdk.trace.export import (
    SimpleExportSpanProcessor,
)

trace.set_tracer_provider(TracerProvider())

cloud_trace_exporter = CloudTraceSpanExporter(
    project_id='my-gcloud-project',
)
trace.get_tracer_provider().add_span_processor(
    SimpleExportSpanProcessor(cloud_trace_exporter)
)
tracer = trace.get_tracer(__name__)
with tracer.start_as_current_span('foo'):
    print('Hello world!')

Metrics

import time

from opentelemetry import metrics
from opentelemetry.exporter.cloud_monitoring import (
    CloudMonitoringMetricsExporter,
)
from opentelemetry.sdk.metrics import Counter, MeterProvider

metrics.set_meter_provider(MeterProvider())
meter = metrics.get_meter(__name__)
metrics.get_meter_provider().start_pipeline(
    meter, CloudMonitoringMetricsExporter(), 5
)

requests_counter = meter.create_metric(
    name="request_counter",
    description="number of requests",
    unit="1",
    value_type=int,
    metric_type=Counter,
    label_keys=("environment"),
)

staging_labels = {"environment": "staging"}

for i in range(20):
    requests_counter.add(25, staging_labels)
    time.sleep(10)
