Getting only the CPU % Use with key system.cpu.util

[Molusco]

Hi, is there a way to get only the CPU % usage with the line below, not the idle, interrupt, etc?

items= zh.item.get(output=['hostid', 'name' , 'key_'], search={'key_':'system.cpu.util'})

I Want to get only these lines

CPU Use % system.cpu.util 0.0959

Not these ones

CPU $2 time system.cpu.util[,idle] 99.7602

CPU $2 time system.cpu.util[,interrupt] 0.0000
