Overview
Metrics provide a near real-time stream of data, informing operators and stakeholders about the functions the system is performing as well as its health. They provide insight into the performance and behavior of a system. Metrics are quantitative measurements of a system's state and can be used to track various aspects of a system, such as resource usage, response times, error rates, and more.
