Pandora's Flask

A worked example of integrating Prometheus monitoring with a Flask app running in the common nginx + uwsgi + Flask stack.

See the related blog post.

You'll need:

• nginx for your platform (we used 1.14.0);
• Python development libraries to build uWSGI;
• virtualenv to build in.

If you want to make test, you'll need tox as well (we used 2.5.0).

Then you should be able to get going with

make run

Which will start the app running under nginx + uwsgi.

You can then visit http://localhost:8040/ and look around, or CTRL-C to bring everything down again.

Once everything's running, you can point a test Prometheus at http://localhost:9040/metrics to scrape the monitoring data.

Directory layout:

• bin/ - some helper scripts;
• conf/ - nginx and uwsgi configuration;
• html/ - a simple index for the app;
• pandoras_flask/ - Python app code;
• tests/ - simple tests.

Let us know if you run into issues getting this demo going, or if you find problems in how we've set things up. Thanks!
