Metrics Reference
Overview
This section provides a complete reference of all available metrics, along with a concise description of what each metric represents. These metrics expose operational, performance, traffic, and system-level insights and can be used for monitoring, analytics, and alerting. These metrics are available per listener or backend or both as applicable. The metrics are exposed in prometheus format and support scraping.
