Quick and dirty ping interval tester for sysadmins

Ping-Tester.bat

:: --- Turn off output in console at initialization ---
@echo off


:: --- Set the ping interval ---
set INTERVAL=30


:: --- Set the output path ---
set OUTPUTDIR=C:\PING
set OUTPUTFILE=result.txt


:: --- Internal network to ping ---

:: Start with the router
set IPROUTER=192.168.1.1
set ROUTERNAME=Router

:: Any other devices and device names in 2 Arrays
:: PiHole
set DEVICE[0]=192.168.1.10

I needed this for a quick test on why my network was having issues, wanted to know what caused it... A friend came in and gave me a simplified version of this, which I've since turned into this little script for sysadmins to use... It basically goes through 2 arrays for cloud and for local devices in your network to ping, and displays in the console whether it was timed out, an unknown host, unreachable or succesful, all of the pings are kept in the output log.

Just alter or add the variables at the top of the file like how they are used now.

The interval will make it automatically ping every x amount of seconds so that you can check whether your network is stable.

I'll create a POSIX compliant UNIX variant later in case a sysadmin needs to execute this on a UNIX system instead.
Maybe even a Powershell variant eventually.

It might make sense to switch the 2 loops around, so that the internal network is tested before the cloud is tested.
Unless the first thing you want to know is whether you are online ofcourse.
