allisnd/monitoring-example

Accompanying repo to go with tutorial video series on monitoring a Spring Boot application.

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.
