Understanding PromQL Course Overview

The "Understanding PromQL" course is designed to provide a comprehensive exploration of Prometheus Query Language (PromQL), equipping learners with the knowledge to effectively query and analyze time-series data within Prometheus. The course begins with an Introduction to PromQL, outlining its significance and how it integrates with Prometheus. It then dives into the Big Picture of PromQL, discussing its execution, Use Cases, and practical applications.

A Data Model Refresher module revisits the time-series data model and metric types to ensure a strong foundational understanding. Basic Querying covers hands-on querying techniques, including rate calculations, aggregation, and using tools like PromLens. An Interlude delves into language theory, providing insights into PromQL's structure and various expression types.

Advanced Querying techniques are then explored, teaching learners to work with histograms, set operations, and perform more complex tasks like anomaly detection and inspecting scrape health. Overall, the course is tailored to enhance the proficiency of users in leveraging PromQL for monitoring and alerting, thereby improving system observability and reliability.
