How to Retrieve CPU Usage in Go with goprocinfo?

Retrieving CPU Usage in Go

Your Go program requires real-time information on the CPU usage of both system and user processes. To achieve this, consider employing the goprocinfo package: https://github.com/c9s/goprocinfo.

Implementing the Solution

The goprocinfo package seamlessly handles the intricate parsing involved in extracting CPU usage data. Its usage syntax is exemplified below:

stat, err := linuxproc.ReadStat("/proc/stat")
if err != nil {
    t.Fatal("stat read fail")
}

for _, s := range stat.CPUStats {
    // s.User
    // s.Nice
    // s.System
    // s.Idle
    // s.IOWait
}

This code snippet effectively retrieves CPU usage data from the "/proc/stat" file, making it available for further processing within your program.
