macOS CPU Info and Processes

This repository provides Go packages to retrieve CPU information and top processes on macOS.

Packages

The project is divided into two packages:

1. cpuinfo: Provides functions to get CPU cores and usage information.
2. processes: Provides functions to retrieve the top processes by CPU usage.

cpuinfo Package

Functions

getDarwinCPUInfo() (int, float64)

Retrieves the number of CPU cores and the current CPU usage.

Returns:

• int: Number of CPU cores.
• float64: Total CPU usage (user + system).

getDarwinCPUCores() int

Retrieves the number of CPU cores using runtime.NumCPU() and as a fallback, the sysctl command.

Returns:

• int: Number of CPU cores.

getDarwinCPUUsage() (float64, error)

Retrieves the current CPU usage by executing the top command.

Returns:

• float64: Total CPU usage (user + system).
• error: Error encountered during execution, if any.

Example Usage

package main

import (
    "fmt"
    "cpuinfo"
)

func main() {
    cores, usage := cpuinfo.GetDarwinCPUInfo()
    fmt.Printf("CPU Cores: %d\n", cores)
    fmt.Printf("CPU Usage: %.2f%%\n", usage)
}
