February 2026 focused on expanding monitoring coverage for Cisco Secure Firewall devices in the librenms/librenms repository. Key enhancement delivered: device discovery and SNMP integration for Cisco Secure Firewall 4215, enabling automated onboarding, discovery, and SNMP data collection. This involved adding an OID, generating SNMP records, and creating a dedicated JSON-based discovery/config for the 4215 model. No major bugs were reported for this period; the work prioritized reliable, scalable monitoring and smoother onboarding for new firewall models. Overall, these changes improve visibility, alerting accuracy, and data quality for Cisco Secure Firewall assets, supporting faster MTTR and better capacity planning. The implementation also demonstrates robust collaboration and adherence to version-controlled, traceable delivery.
