This MKP adds an SNMP-based check to monitor the total PoE power of network switches using the POWER-ETHERNET-MIB. The service “PoE total” shows nominal PoE capacity, current power consumption and percentage utilization, and exposes metrics (poe_used_watts, poe_total_watts, poe_usage_pct) for graphs and perf-o-meters. Warning and critical thresholds can be configured per host via a dedicated WATO ruleset.
