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