opentelemetry-ext-flask 0.3a0

Flask tracing for OpenTelemetry (based on opentelemetry-ext-wsgi)

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 instrument_app

app = Flask(__name__)
instrument_app(app)  # This is where the magic happens. ✨

@app.route("/")
def hello():
    return "Hello!"

if __name__ == "__main__":
    app.run(debug=True)
