[FIXED] Ignore some Flask routes in Opentelemetry

Issue

I have a generic flask application. The application is instrumented using opentelemetry-instrumentation-flask, I am shipping this data with the opentelemetry-exporter-otlp to an Elastic APM server. This is all working fine and it is done as the documentation shows.

There are some endpoints of the application that I would like not to track with the instrumentation, as they are noisy and add little-to-no value for me (For example, health endpoints). I want the instrumentation to ignore them, but I cannot find how.

How can this be done? I have been checking the documentation for Python and after searching over the internet, I could not find any clear answer about how this could be done... because I believe this must be doable.

Solution

You can do that using environment variable OTEL_PYTHON_FLASK_EXCLUDED_URLS. It takes a comma separated regular expressions for urls you want to exclude.
