Client-side library that can be used for distributed trace collection from Python apps via TCP (HTTP) to Jaeger.
See the OpenTracing Python API_ for additional detail.
.. code-block:: bash
pip3 install async-jaeger
Programmatically
The OpenTracing API defines a `sampling.priority` standard tag that
can be used to affect the sampling of a span and its children:
.. code-block:: python
from opentracing.ext import tags as ext_tags
span.set_tag(ext_tags.SAMPLING_PRIORITY, 1)
Via HTTP Headers
Jaeger Tracer also understands a special HTTP Header jaeger-debug-id,
which can be set in the incoming request, e.g.
.. code-block:: bash
curl -H "jaeger-debug-id: some-correlation-id" http://myhost.com
When Jaeger sees this header in the request that otherwise has no tracing context, it ensures that the new trace started for this request will be sampled in the "debug" mode (meaning it should survive all downsampling that might happen in the collection pipeline), and the root span will have a tag as if this statement was executed:
.. code-block:: python
span.set_tag('jaeger-debug-id', 'some-correlation-id')
This allows using Jaeger UI to find the trace by this tag.

Security News
Elastic’s return to open source with the AGPL license has been met with skepticism, as many developers see it as a strategic move rather than a genuine effort to restore user trust and freedoms.
Security News
A new "revival hijack" supply chain attack targets deleted Python packages, with an estimated 22K packages at risk. Socket can detect and block hijacked packages that have added malicious code.
