Prometheus Alerting and Monitoring

We learn the basics of Prometheus so that you can get started as soon as possible, and to follow the exercises, try them out for yourself and you can see it working. In this course we will quickly build a bare bones Prometheus server from scratch, in the cloud and on your own Ubuntu 25.04 LTS. We will keep it simple and set it up on a default, unrestricted, un-customised Ubuntu 25.04 LTS. You will then be able to match what you see in the videos and copy/paste directly from my documentation and see the same result. Once you have the basic experience of seeing Prometheus work, you will be able to problem solve in a more directed manner, and apply your knowledge to other operating systems in the future. At the end of the course, you will have a basic Prometheus setup, which will be in the cloud, behind a reverse proxy, with SSL, a domain name, Basic Authentication, with several custom recording rules, several alerting rules, several node exporters local and external, an alert manager that can send emails via an external SMTP service, a Grafana install, and configured with the Prometheus Data source and several dashboards.
