It would be nice to have prometheus installed somewhere

Demo site

We provide demo site for full monitoring solution based on prometheus and grafana. Repository with code and links to running instances is available on github and site is hosted on DigitalOcean.

Local Testing

The preferred way of locally testing the role is to use Docker and molecule (v3.x). You will have to install Docker on your system. See "Get started" for a Docker package suitable to for your system. Running your tests is as simple as executing molecule test.

Continuous Integration

Combining molecule and circle CI allows us to test how new PRs will behave when used with multiple ansible versions and multiple operating systems. This also allows use to create test scenarios for different role configurations. As a result we have a quite large test matrix which can take more time than local testing, so please be patient.
