I have implemented ELK stack for logging solutions and aslo set up metricbeat for measuring server performance. I stumbled on system module's "system.cpu.user.pct" which is the system's cpu usage. Now, I need to understand what are the other fields that contribute in this value. I have other fields such as **"system.cpu.cores","system.cpu.idle.pct","system.cpu.iowait.pct","system.cpu.irq.pct","system.cpu.nice.pct","system.cpu.softirq.pct","system.cpu.steal.pct","system.cpu.system.pct","system.cpu.user.pct"** under the **metric set cpu**. But most of them have value "0". Although i will run a stress test to see if these 0 values change. I am trying to understand:
- Does the field "system.cpu.user.pct" represent the server usage
- If yes, what fields actually contribute to the changing values of "system.cpu.user.pct"

`cpu.user` means all processes consume the cpu in their user mode, and `cpu.system` means all processes consume the cpu in their kernel mode. Usually, `user+system+idle` should be close to 100%.
You can search `/proc/stat` in [proc(5)](http://man7.org/linux/man-pages/man5/proc.5.html) for more.

@PChou Thank you for the quick response, This answers the first part of my question. Now, can you please tell me what are the **other fields from metricbeat that will affect this server usage( user+system+idle )**. As in, I have other fields as mentioned above. So, with increased stress do the values change respectively thereby contributing to the server usage?
