Result:

As shown in the figure below, it will be carried out at the same time，system.stat The values of [CPU, US] and vmstat,It is found that the US of CPU is very different. As shown in the figure below**

You are correct on the behavior of this key. It's not reporting a correct status. The key will be removed from template.

To measure a user time for CPU, kindly use item key:

system.cpu.util[user,,,physical]

On AIX platform, can I use the project key 【system.cpu.util】?

Comment by bangzhong.xing [ 2021 May 10 ]

When the actual cpu load is greater than 20%, the value is normal
