Implement library github.com/shirou/gopsutil/process under the system package. The library will handle OS compatibility.

1. Get a list of all system processes
2. Parse each process for Name, CPU Percent, Memory Percent, PID, PPID, and Username into a string
3. Append the string to an array

Mostly working example:

package main

import (
	"fmt"

	"github.com/shirou/gopsutil/process"
)

func main() {
	processes, err := process.Processes()
	if err != nil {
		return
	}

	for _, proc := range processes {
		pid := proc.Pid

		ppid, _ := proc.Ppid()

		name, err := proc.Name()
		if err != nil {
			name = "UNKNOWN"
		}

		username, err := proc.Username()
		if err != nil {
			username = "UNKNOWN"
		}

		var cpuPct int
		cpuFloat, err := proc.CPUPercent()
		if err == nil {
			cpuPct = int(cpuFloat)
		}

		var memPct int
		memFloat, err := proc.MemoryPercent()
		if err == nil {
			memPct = int(memFloat)
		}

		fmt.Printf("pid=%d ppid=%d name=%s user=%s cpu_pct=%d mem_pct=%d\n", pid, ppid, name, username, cpuPct, memPct)
	}
}

JSON output:

"processes": ["pid=191321 ppid=191281 name=code user=timski cpu_pct=5 mem_pct=0","pid=173684 ppid=2 name=kworker/u24:7-kcryptd/254:0 user=root cpu_pct=0 mem_pct=0","pid=158019 ppid=59419 name=/usr/bin/python3 user=timski cpu_pct=0 mem_pct=0","pid=66657 ppid=66570 name=slack user=timski cpu_pct=2 mem_pct=0"]

Implement command lsmod | grep -v Module under the system package.

1. Check if the system is Linux.
2. Parse the output of lsmod | grep -v Module
3. Remove extra tabs/spaces between columns
4. Store List of Key Values as a string array

Raw output:

pinctrl_intel          28672  2 pinctrl_cannonlake
wmi                    32768  4 intel_wmi_thunderbolt,wmi_bmof,msi_wmi,mxm_wmi
video                  49152  2 msi_wmi,i915

JSON output:

"loaded_kernel_modules": ["pinctrl_intel 28672 2 pinctrl_cannonlake", "wmi 32768 4 intel_wmi_thunderbolt,wmi_bmof,msi_wmi,mxm_wmi", "video 49152 2 msi_wmi,i915"]

Implement command sysclt -a under system package.

1. Check if the system is not Windows (Run on *NIX only)
2. Parse the output of sysctl -a
3. Store List of Key Values as a string array

Raw output:

vm.swappiness = 1
vm.unprivileged_userfaultfd = 1
vm.user_reserve_kbytes = 131072

JSON output:

"sysctl": ["vm.swappiness = 1", "vm.unprivileged_userfaultfd = 1", "vm.user_reserve_kbytes = 131072"]

Detect Cloud Service Provider (CSP) and if service is within a container.

Implement command dmidecode --string chassis-type under the system package. The command should only run on Linux.

1. Run command
2. Lower case the output, you should see something like Other, Laptop, Notebook, Portable, etc.

JSON output:

"chassis_type": "other"

Convert this current CircleCI CI project into a GitHub Actions project.

Implement some of the CI technologies we implemented in our reference projects.

Implement command systemctl list-timers --all --no-pager | grep -v 'NEXT\|listed' under system package.

Check if the system is not Windows (Run on Linux only)
Parse the table output of systemctl
Store List of table entries
