Prometheus

Prometheus is a Cloud Native monitoring application.

To instrument our Python code we need to manipulate the metrics each time a new HTTP request is received.

See the application for more details.

This project is automatically built by Docker Automated Builds.

To build manually:

docker build -t python-app .
