Zenoss for monitoring HVAC units

Hello,

Im new to Zenoss and I have one special question. Im going to have a hundreds of HVAC unist with analogs inputs/outputs (temperatures, fan votages and etc.) and discrete inputs/outputs. Is possible to modify Zenoss to monitoring this units? Is Zenoss good for this? Available procols is Modbus and in close future also SNMP or something alse can be added.

Thanks, Jirka
