Azure Core Tracing OpenCensus client library for Python¶
Install the opencensus python for Python with pip:
pip install azure-core-tracing-opencensus --pre
Now you can use opencensus for Python as usual with any SDKs that is 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
The opencensus threading plugin is installed with this package
There is no explicit context to pass, you just create your usual opencensus and 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.).
from opencensus.ext.azure.trace_exporter import AzureExporter from opencensus.trace.tracer import Tracer from opencensus.trace.samplers import AlwaysOnSampler from azure.storage.blob import BlobServiceClient exporter = AzureExporter( instrumentation_key="uuid of the instrumentation key (see your Azure Monitor account)" ) tracer = Tracer(exporter=exporter, sampler=AlwaysOnSampler()) with tracer.span(name="MyApplication") as span: client = BlobServiceClient.from_connection_string('connectionstring') client.delete_container('mycontainer') # Call will be traced
