CPU busy time

[jvillain]

I am trying to create a "cpu busy time" calculated item in the "Linux OS template" which would just flip the idle time graph upside down because my manager is to stupid to cope with idle time. I am trying to create a calculated item that would be 100 - idle time.

I have tried the following

100-last("system.cpu.util[,idle]")
100 - last("system.cpu.util[,idle]")
"100-last("system.cpu.util[,idle]")"
100 - last(system.cpu.util[,idle])

All come back with bad syntax errors. Can any one tell me what I am doing wrong? Thanks in advance.

I set up a test item using

100-last("system.cpu.util[,idle]")

and it worked just fine on zabbix 3.0.4.
