Which of the following best describes a metric in Datadog?

A metric in Datadog is best described as a numerical value representing system resource usage. Metrics are quantitative measurements that capture various aspects of system performance, such as CPU usage, memory utilization, or network traffic. These values are collected at regular intervals and provide valuable insights into the operational health and performance of systems, applications, and services.

Metrics are fundamental to monitoring and analyzing system behavior over time. They enable users to identify trends, anomalies, and performance bottlenecks within their infrastructure. By visualizing these metrics through graphs and dashboards, Datadog allows teams to track changes in system performance effectively.

While visual reports of performance trends, descriptions of application architecture, and configuration settings for alerts are all important components of a comprehensive monitoring strategy, they do not constitute metrics themselves. Instead, they depend on metrics to provide the necessary data for analysis, reporting, and alerting.
