Developed production-ready parsing for Google Cloud Proxy Network Load Balancer connection logs within the open-telemetry/opentelemetry-collector-contrib repository, focusing on enhancing observability and security for GCP network traffic. The work introduced a dedicated parser in Go that translates IANA protocol numbers, captures connection timing and byte counts, and surfaces detailed resource metadata such as backend and network names. By mapping these details to OpenTelemetry attributes and ensuring compatibility with l4_proxy_rule logs, the implementation improved the accuracy of protocol labeling and data exposure. Comprehensive unit and golden tests, along with updated documentation, validated the parsing logic and supported robust backend development practices.
