Fathil Arham developed a configurable metrics collection feature for the gofiber/contrib repository, introducing a WithoutMetrics option that allows teams to selectively disable metrics for request duration, size, and active requests. Working in Go, he integrated this option through both application configuration and Fiber middleware, ensuring that metrics are only recorded when desired. The implementation included comprehensive unit tests to validate the new behavior and maintained backward compatibility by preserving default metrics collection. By focusing on observability and configuration management, Fathil’s work enables performance-focused deployments while giving teams granular control over telemetry overhead in their backend systems.

In May 2025, gofiber/contrib delivered a configurable WithoutMetrics option to selectively disable metrics collection for request duration, size, and active requests across both configuration and Fiber middleware. This provides teams with control over observability overhead, enabling performance-focused deployments while preserving metrics when needed. The work includes wiring the option through config and middleware, plus unit tests validating the behavior. This change reduces telemetry overhead when metrics are disabled and improves signal quality when enabled. Commit history demonstrates a clear, testable progression.
