Powershell or Batch script to ping IP's for a certain lenght of time

Here's a batch script; it doesn't stop after 8 hours, but then again, it will only log status changes, so the log shouldn't be too big. Just double-click it, it will ask for a host to ping and then create a log file in the script's folder.

@echo off
setlocal
mode con cols=40 lines=25
if "%~1"=="" (
	set /p IP=Name or IP: 
) else (
	set IP=%~1
)
title Ping %IP%
set LogFile=%~dpn0-%IP%.log
set Lost=X
:loop
ping.exe -n 1 %IP% | find /i "TTL" >NUL
if errorlevel 1 (
	if not %Lost%==1 (
		color 4F
		echo - Down: %Date% %Time: =0%
		>>"%LogFile%" echo - %Date% %Time%
		set Lost=1
	) 
) else (
	if not %Lost%==0 (
		color 2F
		echo + Up: %Date% %Time: =0%
		>>"%LogFile%" echo + %Date% %Time%
		set Lost=0
	)
	ping.exe localhost -n 2 >NUL
)
goto :loop

will this work pinging 3 different IP's?

No, but you can just start three different instances.

Bob,
I am pinging 3 different IP's (no DNS name so has to be IP) and would want to ping or test connection from 07:00am EST to 5:00pm EST (US).  I would ideally want a start and stop time.

The output could be whatever is easiest to tell me if the test or ping failed and when or what OBDA stated as to log only failures if that's possible.

How often do you want it to run?  Once a minute?  Every five seconds?

OK, here's what I came up with.

$serverList = "192.168.50.154","192.168.50.239","192.168.55.254"
#$stopTime = Get-Date -Hour 17 -Minute 0 -Second 0
$stopTime = (Get-Date).AddSeconds(60)
$pass = 0

$results = do {
    $now = Get-Date
    $pass++
    foreach ($server in $serverList)
    {
        $responseTime = ((Test-Connection $server -ErrorAction SilentlyContinue).ResponseTime | Measure-Object -Average).Average
        Write-Verbose "$("[{0:D5}] {1,16} {2,7}" -f $pass, $server, $responseTime)"
        [PSCustomObject]@{
            Computer = $server
            TimeStamp = $now.ToShortTimeString()
            Time = $responseTime
        }
    }
    Start-Sleep -Seconds 4
} until ($now -gt $stopTime)

# Sample outputs - pick one or more, your choice
$results
$results | Format-Table -AutoSize
$results | Out-GridView
$results | Export-Csv -Path .\foo.csv -NoTypeInformation -Encoding ASCII
$results | Out-File -FilePath .\foo.txt -Encoding ASCII
$results | Export-Clixml -Path .\foo.xml -Encoding ASCII

Awesome   i will give that a whirl and get back to you as soon as I can.  Cheers.

Any updates?

Not yet.  Been off work and my home lab is out of comish right now.  I will try this as soon as i get back to work.  Thanks very much for following up.  I will keep you posted.

Bob,
I'm back to normal today.  I will start testing the script today.  Sorry for all the delays after your hard work.

Were should i input the $VerbosePreference=2 option in the script if i did want to watch it interactively?

You can put it at the top of the script.  Or you can enter it in the console window before running the script.

So i am testing and have 2 questions:

1. i noticed in the results it doesn't have the ping time <1ms etc...  Is there a way for that to show up in results?

2.  When i change the time in line 2 for 1 or 2 (which i thought where hours) it runs once and stops.  How does that line work?  How can i set it to run for 23 hours?  Also, when i did set the time in line 2 to 23 hours and manually stopped the script, it didn't write the log.  

Any ideas?

Your script works great Bob !
THanks.

Thanks Bob.  Sorry for the delayed closing of this.  Appreciate all your assist.
