OpenTelemetry Flask Instrumentation¶
This library builds on the OpenTelemetry WSGI middleware to track web requests in Flask applications. In addition to opentelemetry-instrumentation-wsgi, it supports flask-specific features such as:
The Flask endpoint name is used as the Span name.
http.routeSpan attribute is set so that one can see which URL rule matched a request.
from flask import Flask from opentelemetry.instrumentation.flask import FlaskInstrumentor app = Flask(__name__) FlaskInstrumentor().instrument_app(app) @app.route("/") def hello(): return "Hello!" if __name__ == "__main__": app.run(debug=True)
