As the 2nd oldest project in the CNCF, you have probably heard about Prometheus before. Prometheus is the de facto standard in cloud-native metrics monitoring and beyond, mainly because Kubernetes is designing its custom metrics engine for Prometheus. Nevertheless, the project maintainers will introduce you from the very beginning, followed by a deep dive into its internal and a list of the exciting new features that have been released recently or are in the pipeline. You will learn about many opportunities to use Prometheus, and we will cover a mix of introduction content, a deeper dive into current developments, and open Q&A at the end. We can even tempt you to contribute to the project yourself.
