This library allows tracing requests for Django applications.
pip install opentelemetry-instrumentation-django
To exclude certain URLs from being tracked, set the environment variable OTEL_PYTHON_DJANGO_EXCLUDED_URLS
with comma delimited regexes representing which URLs to exclude.
For example,
export OTEL_PYTHON_DJANGO_EXCLUDED_URLS="client/.*/info,healthcheck"
will exclude requests such as https://site/client/123/info
and https://site/xyz/healthcheck
.
To extract certain attributes from Django's request object and use them as span attributes, set the environment variable OTEL_PYTHON_DJANGO_TRACED_REQUEST_ATTRS
to a comma
delimited list of request attribute names.
For example,
export OTEL_PYTHON_DJANGO_TRACED_REQUEST_ATTRS='path_info,content_type'
will extract path_info and content_type attributes from every traced request and add them as span attritbues.

The instrumentation supports specifying request and response hooks. These are functions that get called back by the instrumentation right after a Span is created for a request and right before the span is finished while processing a response. The hooks can be configured as follows:
def request_hook(span, request): pass def response_hook(span, request, response): pass DjangoInstrumentation().instrument(request_hook=request_hook, response_hook=response_hook)
