This plugin monitors power supply status for network devices (switches) using SNMP. It detects the operational state of each power supply unit (PSU) and reports failures or degraded conditions. The plugin only evaluates the status reported by the device. The plugin is able to recognize and monitor all power supplies in stacked switch environments, providing per-PSU status across all stack members. Features: - Per-PSU status monitoring (OK / CRIT) - Detection of failed or redundant power supplies - Support for stacked switches (all PSUs across the stack are discovered) - Serial number display for each PSU (if available) Requirements: - SNMP enabled on the target device Tested on: - LANCOM GS-4554X and similar devices Compatible with Checkmk 2.2+ This is an initial version of the plugin. Contributions, improvements, and feedback are very welcome.
