If you're brand new to Prometheus and want a quick and easy introduction, this video will do just that in 13 minutes.
In the video I cover:
- Prometheus and its components
- Different Prometheus metric types
Then during the hands on you will:
- Create a Python / FastAPI based server which makes a prometheus metric available
- Configure Prometheus to retrieve (aka pull or scrape) that metric into Prometheus
- Understand how to troubleshoot prometheus connection errors to the endpoints it is trying to scrape (aka. targets)
- Start Prometheus and view the metric
- Update the metric and watch the the new value be shown in Prometheus
Open Source Code
All of the code I use is open source and available here: https://github.com/agardnerit/prometheus-for-beginners
