Welcome to this repository, which goes along with the Tom Gregory Tech Youtube series and the tomgregory.com blog series!
There are 4 parts to the series:
- Part 1: Fundamentals (blog|video)
- Part 2: Prometheus (blog|video)
- Part 3: Rules & Alerting (blog|video)
- Part 4: Visualisation & Graphing (blog|video)
Each part is tagged in the repository, so you can checkout the code and follow along with the video/blog post. e.g.
git checkout part2
Note that part 1 isn't tagged as it doesn't have a code example component.
