Microsoft Azure Azure Core OpenTelemetry plugin Library for Python
Install the Azure Core OpenTelemetry Tracing plugin for Python with pip:
pip install azure-core-tracing-opentelemetry
Now you can use OpenTelemetry for Python as usual with any SDKs that are compatible with azure-core tracing. This includes (not exhaustive list), azure-storage-blob, azure-keyvault-secrets, azure-eventhub, etc.
You don't need to pass any context, SDK will get it for you
There are two ways to enable the tracing plugin in code:
from azure.core.settings import settings
from azure.core.tracing.ext.opentelemetry_span import OpenTelemetrySpan
settings.tracing_implementation = OpenTelemetrySpan
or
from azure.core.settings import settings
settings.tracing_implementation = "opentelemetry"
Alternatively, if you have the latest version of azure-core installed, you can also set the following environment variable to enable tracing with OpenTelemetry:
AZURE_SDK_TRACING_IMPLEMENTATION=opentelemetry
There is no explicit context to pass, you just create your usual opentelemetry tracer and call any SDK code that is compatible with azure-core tracing. This is an example using Azure Monitor exporter, but you can use any exporter (Zipkin, etc.).
# Declare OpenTelemetry as enabled tracing plugin for Azure SDKs
from azure.core.settings import settings
settings.tracing_implementation = "opentelemetry"
# In the below example, we use a simple console exporter, uncomment these lines to use
# the OpenTelemetry exporter for Azure Monitor.
# Example of a trace exporter for Azure Monitor, but you can use anything OpenTelemetry supports
# from azure.monitor.opentelemetry.exporter import AzureMonitorTraceExporter
# exporter = AzureMonitorTraceExporter(
# connection_string="the connection string used for your Application Insights resource"
# )
# Regular open telemetry usage from here, see https://github.com/open-telemetry/opentelemetry-python
# for details
from opentelemetry import trace
from opentelemetry.sdk.trace import TracerProvider
from opentelemetry.sdk.trace.export import ConsoleSpanExporter
from opentelemetry.sdk.trace.export import SimpleSpanProcessor
# Simple console exporter
exporter = ConsoleSpanExporter()
trace.set_tracer_provider(TracerProvider())
tracer = trace.get_tracer(__name__)
trace.get_tracer_provider().add_span_processor(
SimpleSpanProcessor(exporter)
)
# Example with Storage SDKs
from azure.storage.blob import BlobServiceClient
with tracer.start_as_current_span(name="MyApplication"):
client = BlobServiceClient.from_connection_string('connectionstring')
client.create_container('my_container') # Call will be traced
The Azure Monitor OpenTelemetry Exporter can be found in the azure-monitor-opentelemetry-exporter package.
With the Azure Core OpenTelemetry Tracing plugin enabled, HTTP requests made by Azure SDK clients are typically instrumented via the DistributedTracingPolicy automatically. Since Azure Core handles HTTP instrumentation for Azure service calls, automatic HTTP instrumentation from other libraries such as opentelemetry-requests-instrumentation are suppressed to avoid duplicate spans from being created.
This client raises exceptions defined in Azure Core.
More documentation on OpenTelemetry configuration can be found on the OpenTelemetry website

OpenTelemetrySpan typing to correctly implement the AbstractSpan protocol. (#31943)context keyword argument for passing in context headers of a parent span. This will be the parent context used when creating the span. (#30411)x-ms-client-request-id -> az.client_request_id,x-ms-request-id -> az.service_request_id,http.user_agent -> user_agent.original,message_bus.destination -> messaging.destination.name,peer.address -> net.peer.name,opentelemetry-api dependency bumped to 1.12.0.azure-core dependency bumped to 1.24.0.Link and SpanKind can now be added while creating the span instance.DefaultSpan sometimes throws an AttributeError.link and link_from_headers now accepts attributes.
