What is the item key ?

Did you double check that you are looking on the same host ?

Hi. I use "system.cpu.util[,system,avg1]" key.
It seems, it's not zabbix_agent problem. The System Performance monitoring shows right counters such as like zabbix , but The Task Manager and procexp shows the same cpu utilization. I think the problem is in the Windows.
You cat see it in the picture cpu_util.

Yeas, zabbix agent uses that perf counter, so it's correct.

Would be nice if figure out and describe here why Task manager shows ~64% - what does it include.
