This section contains a sample of using Prometheus to instrument a Flask application to emit Service Level Indicator metrics.

1. Many samples require extra libraries to be installed. If there is a requirements.txt, you will need to install the dependencies with pip.

   pip install -t lib -r requirements.txt
   

2. Use main.py to run the sample:

   python main.py
   

3. Visit http://localhost:8080 to view your application.

4. Visit http://localhost:8080/metrics to view your metrics.
