Understanding Prometheus Metric Types | Meaning and Usage (Gauge, Counter, Summary, Histogram)

This video explains the four different metric types in Prometheus: Gauges, Counters, Summaries, and Histograms. It goes into the meaning of each type, explains how to use each type in instrumentation, and how they show up in the exposition format. It also touches on what you have to watch out for when querying each metric type with PromQL.
