During their work on the prometheus/snmp_exporter repository, Erlang Gayudipradana focused on improving the reliability of SNMP metric collection for Sophos XG devices. They addressed a 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 prevented misconfiguration and improved the accuracy of monitoring data by aligning the build and release artifacts with the intended file format. Erlang utilized Makefile scripting and build systems expertise to deliver a targeted fix, enhancing data integrity and operator confidence in SNMP exporter deployments for Sophos XG.
