git clone ... tornad-prometheus
cd tornad-prometheus
pip install -r requirements.txt
python app/app.py

Then go to http://127.0.0.1:8888

Prometheus stats

Basic metrics exported are:

• Garbage collector objects
• Endpoints number of time called
• Number of total requests
• Total seconds spend in each request

Examples:
