PROFILE
Jeff Engleman
Over a two-month period, contributed to the librenms/librenms repository by developing advanced monitoring features for power distribution units (PDUs). Delivered Sentry4 PDU cord balance monitoring by extending the sentry4.json schema with a new percent data type, enabling granular health metrics for each cord. Enhanced observability for Chatsworth PDUs by implementing branch-level monitoring, updating YAML-based discovery definitions and SNMP simulation data to capture detailed branch metrics such as current, voltage, and power. Demonstrated expertise in configuration management, device monitoring, and SNMP data modeling, focusing on maintainable, traceable changes that improve proactive diagnostics and operational visibility for critical infrastructure.

May 1, 2025Month: 2025-05 | Repository: librenms/librenms. Focused on elevating PDU observability by delivering branch-level monitoring for Chatsworth PDUs and extending the discovery data model to capture granular branch metrics. Key features delivered: - Branch Monitoring for Chatsworth PDUs: Adds branch-level monitoring by updating discovery YAML and SNMP simulation data to capture branch ID, current, voltage, power, consumed power, and status. Commit: 2608792eff60def1cffc377d03d94d24c934d892 (Added branch monitoring for chatsworth pdus (#17589)). Major bugs fixed: - Not documented for this month in the provided input data. Overall impact and accomplishments: - Improved visibility into branch-level PDU health and power usage, enabling proactive capacity planning, quicker fault isolation, and more accurate SLA reporting. - Streamlined data collection with a focused change set in a single repo, reducing integration risk and accelerating rollout of branch-level metrics. Technologies/skills demonstrated: - YAML-driven discovery configuration and SNMP data modeling - Data simulation for SNMP-based metrics - Version control traceability (commit reference) and focused feature delivery within a mono-repo

Mar 1, 2025March 2025 — librenms/librenms. Key features delivered: - Sentry4 PDU cord balance monitoring: Introduced a new cord balance metric in the PDU discovery definitions and added a new 'percent' data type to the sentry4.json file to capture cord balance per cord, enabling improved visibility into Sentry4 PDU health. Major bugs fixed: - No major bugs reported/recorded for this month (per provided data). Overall impact and accomplishments: - Expanded monitoring coverage for critical Sentry4 PDUs, enabling proactive diagnostics and faster issue resolution. - Supports reliability and uptime goals by providing more granular health indicators for Sentry4 PDUs, reducing mean time to detection for cord-related issues. Technologies/skills demonstrated: - JSON schema extension and data modeling (sentry4.json) to support new metrics. - Monitoring instrumentation and PDU discovery integration. - Git-based change management and traceable commits (cf536a371decff4174cda8e96cbb8b205f8da1a2) and PR tracking (#17242). - Open-source contribution practices and collaborative development workflows.
