Introduction to the Prometheus Monitoring System | Key Concepts and Features

Get a quick high-level overview of the key concepts of the Prometheus monitoring system straight from the co-founder of Prometheus.

This video explains what Prometheus is, what the system architecture looks …like, and what the main features and concepts are that make Prometheus-based monitoring so powerful: the dimensional data model, the text-based metrics transfer format, the PromQL query language, integrated alerting, and service discovery support.

In this video, I explain Prometheus histograms (for now only the “classic” ones that have been in Prometheus for around a decade – I will make a separate video about …the new “native” histograms once they are stable): What are histograms, why are they useful, how can you instrument your service code with histograms, how are histograms exposed as metrics to Prometheus, and how can we query them in PromQL to get quantiles/percentiles, heatmaps, request rates, or average request durations?
