GUI-based tool for monitoring network connectivity through ping tests

This Python script is a simple GUI-based tool for monitoring network connectivity through ping tests. It uses the Tkinter library for the graphical user interface (GUI) and subprocess to run ping commands. Let’s break down the code:

Importing Libraries

import subprocess
from datetime import datetime, timedelta
import time
from tkinter import *
import ipaddress
import re

• The script imports necessary libraries, including subprocess for running external commands, datetime for handling timestamps, time for managing time-related functions, Tkinter for creating the GUI, and ipaddress and re for handling IP addresses and regular expressions.

Function Definitions

def start_ping():
    # Function to start the ping test
    # ... (explained below)

def abort_ping():
    # Function to abort the ping test (currently empty)
    pass

• The script defines two functions: start_ping to initiate the ping test and abort_ping to abort it (currently empty).

GUI Initialization

root = Tk()
root.title("Ping Monitor by School of Iris")

label_1 = Label(root, font="Arial", text="Enter IP or URL", anchor=W)
label_1.grid(row=0, column=0)

ipaddr = Entry(root, font="Arial", width=30, borderwidth=2)
ipaddr.grid(row=0, column=1, columnspan=2)

label_2 = Label(root, font="Arial", text="Enter Device Name", anchor=W)
label_2.grid(row=1, column=0)

device = Entry(root, font="Arial", width=30, borderwidth=2)
device.grid(row=1, column=1, columnspan=2)

label_3 = Label(root, font="Arial", text="Enter Duration (minutes)", anchor=W)
label_3.grid(row=2, column=0)

duration = Entry(root, font="Arial", width=30, borderwidth=2)
duration.grid(row=2, column=1, columnspan=2)

button_start = Button(root, font="Arial", text="START", padx=50, command=start_ping)
# button_abort = Button(root, font="Arial", text="Abort", padx=20, command=abort_ping)
# button_exit = Button(root, font="Arial", text="Exit", padx=20, command=root.quit)
button_start.grid(row=3, column=0, columnspan=3)
# button_abort.grid(row=3, column=1)
# button_exit.grid(row=3, column=2)
statusbar = Label(root, text="Click START for monitoring", bd=1, relief=SUNKEN, anchor=W)
statusbar.grid(row=5, column=0, sticky=W + E, columnspan=3)

• The script initializes a Tkinter window (root) and creates labels, entry fields, and buttons for the GUI.

Function start_ping

def start_ping():
    # ... (previous lines)

    if deviceName and input_IP and minutes:
        if (ip_check or url_check or url2_check):
            if min_check:
                # ... (previous lines)

                while datetime.now() <= endTime:
                    result = subprocess.run(pcommand, capture_output=True, text=True)

                    # ... (previous lines)

                    if result.returncode == 1 and startevent == 0:
                        # ... (previous lines)
                    elif result.returncode == 1 and startevent == 1:
                        pass
                    elif result.returncode == 0 and startevent == 1:
                        # ... (previous lines)
                    elif result.returncode == 0 and startevent == 0:
                        # ... (previous lines)

                statusbar.configure(text='Program Ended')
                # ... (previous lines)

    else:
        # ... (previous lines)

• The start_ping function is called when the “START” button is clicked. It retrieves input values, checks their validity, and initiates a ping test for the specified duration. The ping results are logged into a file, and the program’s progress is displayed in the status bar.

GUI Main Loop

root.mainloop()

• The script enters the Tkinter main loop to handle user interactions and events.

In summary, this script creates a simple GUI using Tkinter to perform ping tests on a specified IP address or URL for a specified duration. It uses subprocess to run the ping command and logs the results to a text file. The GUI allows users to input the target, device name, and test duration, and then start the ping test.
