OpenTelemetry Django Instrumentation

Instrument django to trace Django applications.


from opentelemetry.instrumentation.django import DjangoInstrumentor



Exclude lists

To exclude certain URLs from being tracked, set the environment variable OTEL_PYTHON_DJANGO_EXCLUDED_URLS (or OTEL_PYTHON_EXCLUDED_URLS as fallback) 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.

Request attributes

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.

Request and Response hooks

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):

def response_hook(span, request, response):

DjangoInstrumentation().instrument(request_hook=request_hook, response_hook=response_hook)

Return a list of python packages with versions that the will be instrumented.

The format should be the same as used in requirements.txt or

For example, if an instrumentation instruments requests 1.x, this method should look like:

def instrumentation_dependencies(self) -> Collection[str]:

return [‘requests ~= 1.0’]

This will ensure that the instrumentation will only be used when the specified library is present in the environment.
