Smart pinging tool for windows(with coloring,email,and alerting)

One of the routine activities that I am dealing with is finding better ways to monitor critical servers and services, and helping NOC operators to have better tools for their tasks which is mainly watching over platforms that are critical for my company and me as well.
part of monitoring job is to see whether a server is accessible in a network or not, we have a lot of tools to fulfill this need but as an administrator I have to say pinging is something else.

putting aside all the monitoring tools that I operated in our NOC(Network Operation center) department I wanted to keep this beautiful and somehow traditional administration command called 'ping' in the game, so what I did was to come up with a little bit more sophisticated tool which I call py-ping.

It is not a big thing for sure, It is a python 3x script which is going to do the following:
Asking about the Email you want to send errors and IP that you want to ping or actually monitor
if you dont want to send emails to anywhere, simply ignore email part and press enter

When you put the IP address it is going to show you the result as following:
Green lines if your device is accesibale

red lines if your server is not accessible in any ways

so far it is fine but adding two colors is not worth the trouble, right?
that is why I added another feature which almost every monitoring toll needs

Alerting

the way I managed alerting is that you only need to put a sound file named 'alert.mp3' in the same directory as py-ping.exe file( you can choose your own sound, I put one for you just in case), by default the sound will play for 5 seconds but you can change it as you like in the code.

You can download different warnings for as your alert.mp3 here

Emailing

As I figured it out during these years emailing is always a good feature for a monitoring tool, so I tried to bring it to my little and simple ping tool too. at the beginning you will be asked to put an email address as a destination, if you leave it blank it would not be a problem , but if you put your email address there, you will get an email every time your server goes to critical condition

Downloading

you can download the tool from dropbox here
you just need to unzip it and run the py-ping.exe file

and here you can see the code itself, feel free to edit it anyway and share it anywhere you like(I appreciate it if you mention me as well)

import os
import sys
import time
import signal
import smtplib
from termcolor import colored, cprint
from colorama import init
init()
###Email you want to use as your email address
FROM = "[email protected]"
### YOU CAN SET DESTINATIONS FOR SENDING EMAIL TO   
TO = [""]
TO[0] = input('Send Email to: ')
###SMTP SERVER 
SERVER = "192.168.45.12"
IP = input('IP Address: ')
### title of email
SUBJECT = 'packet lost on ' + IP
PING = 'ping ' + IP + ' -t'
p = os.popen(PING,"r")

### Variable to keep the track of OKs after timeout
got_reply = 0
### Timeout Counter
time_out_counter = 0

### Signal Handler for CRTL + C
def signal_handler(signal, frame):
        while True:
           print()
           print("Thank you guys for using this tool")
           print()
           print("@meysam")
           print("steemit.com")
           sys.exit(0)
signal.signal(signal.SIGINT, signal_handler)

###Function to define green color
def green_color(a):
    cprint(a, 'green', attrs=['bold'], file=sys.stderr )
###Function to define red color
def red_color(a):
    cprint(a, 'red', attrs=['bold'], file=sys.stderr)

    
    
    
while 1:
    line = p.readline()
    line = line.rstrip()
    ### DETECTING NOT OKs
    if 'TTL' not in line:
                    if('Pinging') in line:
                        print(line)
                    else:
                        red_color(line)
                        time_out_counter += 1
                    ### AFTER GETTING 4 TIMEOUT THE WARNING STARTS FOR 5 SECONDS
                    if time_out_counter == 4:
                        os.system('alert.mp3')
                        ### TIME THAT YOU LIKE YOUR WARNING KEEPS GOING
                        time.sleep(5)
                        ###KILLING THE WMPLAYER
                        os.system('Taskkill /IM wmplayer.exe /F > null')
                        ### Handle the error if SMTP server is not accessibale 
                        try:
                            ### Emailing
                            TEXT = 'the server is down'
                            message = """\
From: %s
To: %s
Subject: %s

%s
""" % (FROM, ", ".join(TO), SUBJECT, TEXT)
        
                            # Send the mail
                            server = smtplib.SMTP(SERVER)
                            server.sendmail(FROM, TO, message)
                            server.quit()
                            ### RESETING OKs TO ZERO
                        except:
                            ignore = 1
                        if got_reply >= 3:
                            got_reply = 0
    ### DETECTING OKs
    elif 'TTL' in line:
        green_color(line)
        got_reply += 1
        ### IF YOU GET MORE THAN 2 OKs, TIMEOUT COUNTER WILL RESET TO ZERO
        if got_reply >= 2:
            time_out_counter = 0
        

### @meysam

note that I didn't do much debugging and error handling, if you find some error I would be happy to hear about it and will try to fix it
