Metrics

Metrics software is used to measure, analyze, and improve various aspects of software performance. It can be used for debugging, performance optimization, cost estimation, and quality assurance.

Examples of common metrics include CPU and memory usage; cache hit ratios; response time, latency, throughput (queries per second) for APIs; build success rate and pipeline duration for CD/CI workflows.
