CyberPower UPS Monitor

This tool provides a dedicated monitor for CyberPower UPS devices within Proxmox environments. It polls UPS data such as battery health, runtime, load, voltage, and temperature, offering a unified view of power readiness for virtualization hosts and VMs. It uses SNMP v2c/v3 or device API to collect data, supports multiple UPS devices, and can group devices for consolidated dashboards. The system calculates an estimated runtime from reported capacity and current load, and flags battery degradation when observed runtime diverges from expected values. Historical trends enable capacity planning and proactive maintenance. Alerts can be triggered when battery health or load thresholds are exceeded, enabling timely shutdowns and notifications. The tool supports exporting metrics to CSV/JSON and can push to Proxmox alerting or external monitoring stacks. Use cases include protecting a Proxmox cluster with redundant CyberPower UPS devices, coordinating VM migrations during power events, and auditing UPS performance over time for capacity planning.
