Worked on the grafana/alloy repository to upgrade the squid-exporter component to version 1.13.0, enabling support for newer Squid versions and transitioning metrics export from the deprecated cache_object scheme to an HTTP-based approach. This change improved compatibility and metrics accuracy for Squid deployments, addressing issue #6097 and aligning the exporter with current best practices. The work involved backend development using Go, with careful attention to observability and upgrade readiness across environments. The implementation was thoroughly documented in the commit history, ensuring maintainability and clarity for future contributors working with Go and backend systems in the grafana/alloy project.
