How to Retrieve CPU Usage in Go using the goprocinfo Package?

Retrieving CPU Usage in Go

In Go, monitoring CPU usage is essential for optimizing resource utilization. To accurately determine the CPU usage of both system and user processes, the goprocinfo package provides an efficient solution.

Using goprocinfo, you can obtain detailed CPU statistics by parsing the "/proc/stat" file. The following code snippet demonstrates how to achieve this:

import "github.com/c9s/goprocinfo"

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

for _, s := range stat.CPUStats {
    // s.User represents user processes CPU usage.
    // s.Nice represents nice'd user processes CPU usage.
    // s.System represents system processes CPU usage.
    // s.Idle represents idle CPU usage.
    // s.IOWait represents CPU usage waiting for I/O to complete.
}

This code reads the "/proc/stat" file and parses the CPU statistics. The CPUStats slice contains individual CPU usage statistics for each logical CPU present on the system. Each CPUStat object provides specific values for user, system, idle, and I/O wait usage. By iterating over this slice, you can access the desired CPU usage information.
