Amaury,
If Zabbix is capable of using SNMP OID polling (which I am sure it is), then you could configure a template to poll the extremePethSlotPoeStatus OID of .1.3.6.1.4.1.1916.1.27.1.2.1.8
The switch will respond with one of the following values:
- Initializing - PoE controller is under initialization
- Operational - PoE controller is operation and is ready or providing power
- downloadFail - PoE controller required udate and th e update failed. PoE reset is required to re-update
- invalidFirmware - PoE controller contains invalid firmware
- mismatchVersion - PoE controller update completed, however version mismatches expected, reboot.
- updating - PoE controller is being updated
- invalidDevice - PoE controller detected an invalid/bad PoE device
- notOperational - PoE controller is not yet operational
- other - PoE controller is an undefined state
