Worked on enhancing storage metric reliability for NimbleOS devices within the librenms/librenms repository, focusing on SNMP monitoring and PHP development. Addressed a bug that caused undefined array key exceptions by updating the SNMP walk to include both volUsageHigh and volUsageLow, and corrected storage size calculations using high and low OID values. Improved test coverage by updating nimbleos.snmprec test data, ensuring more accurate and regression-safe validation. These changes resulted in more stable storage metric collection and reduced false positives, providing clearer capacity insights. Demonstrated skills in bug fixing, SNMP MIB handling, and test-driven development throughout the process.
