Boris Neymanov focused on backend stability improvements for the ntop/ntopng repository, addressing reliability issues in the InfluxDB top-timeseries path. He implemented a guarded SNMP lookup mechanism using Lua scripting, ensuring that SNMP device queries only occur when the relevant device tag is present. This approach prevented fatal Lua errors when snmp_utils was unavailable, particularly for non-device schemas, and aligned the behavior with the RRD driver. By introducing compatibility checks for the ntop Pro edition, Boris reduced production risk and support incidents for customers relying on InfluxDB-backed queries. His work demonstrated depth in backend development and Lua integration.
