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
set DEVICENAME[0]=PiHole

:: Home Assistant
set DEVICE[1]=192.168.1.20
set DEVICENAME[1]=Home Assistant

:: Gaming Desktop
set DEVICE[2]=192.168.4.10
set DEVICENAME[2]=Gaming Desktop

:: Mobile Phone
set DEVICE[3]=192.168.1.189
set DEVICENAME[3]=Mobile Phone


:: --- Online servers to ping ---

:: Any other clouds and cloud names in 2 Arrays
:: Google
set CLOUD[0]=8.8.8.8
set CLOUDNAME[0]=Google Servers

:: Cloudflare
set CLOUD[1]=1.1.1.1
set CLOUDNAME[1]=Cloudflare Servers
