During April 2025, Erlang Gayu Pradana focused on enhancing the reliability of SNMP metric collection for Sophos XG devices within the prometheus/snmp_exporter repository. He addressed a critical bug in the build system by updating the Makefile to ensure the correct .mib file, rather than a .txt file, was used during MIB extraction. This adjustment improved the accuracy of metric collection and reduced the risk of misconfiguration or data gaps. Erlang applied his expertise in build systems and Makefile scripting to streamline the extraction flow, demonstrating careful attention to detail and a strong understanding of file handling in monitoring pipelines.
