FS_Sys_Cpu
The directory _sys/proc/cpu exists as a sub-directory to the file system root.
The directory contains cpu usage information.
The files in the sys/proc/cpu directory are listed in the table below:
| File | Description |
|---|---|
| cpu.txt | CPU usage, sorted by PID. |
| cpu-time.txt | CPU usage, sorted by total active time. |
| cpu-usage.txt | CPU usage, sorted by current activity, only shown in live memory analysis. |
| readme.txt | README file. |
Files in the sys/proc/cpu directory are read-only.
The file cpu.txt contains a per-pid view of the process activity.

The example shows the sys/proc/cpu directory on a live target. The WSL window command is watch -n 10 'head cpu-usage.txt' to refresh the cpu usage every 10s.
The sys/proc/cpu sub-directory is implemented as a built-in native C-code plugin. The plugin source is located in the file modules/m_sys_proccpu.c in the vmm project.
