Either the documentation or the template is wrong for AIX for the following items:

kernel.maxfiles
kernel.maxproc
3 times sensor[tempx]
system.boottime
3 times system.cpu.load[avg,x]
system.cpu.util[,nice,avg1]
system.swap.size[,pfree]
system.swap.size[,free]
system.swap.size[,total]

They are in the AIX template (Type Zabbix agent), but the documentation (2.0) says, they're not supported.
