Description:
This is a
small PowerShell script; you can run it from your any windows machine to check
your or any website’s status in every 30 seconds/ any at frequency. (you can change it to your desire time)
And if it (script)
found that the specific webpage is down then it will send you an email that your web
site is down.
But you need
a SMTP server and internet connection.
Use case:
If is there
any scenarios come like, your webpage is going down any how without your
knowledge and you are getting so many complain about it. Then you can implement
this script to monitor your site and take necessary actions.
Here I have
used web page as an "https://www.facebook.com/" and it will check the
status of this page or link in every 30 seconds.
The Script:
Begin {
$web = New-Object System.Net.WebClient
$web.UseDefaultCredentials = $True
$flag = $false
$url = "https://www.facebook.com/"
}
Process {
While ($flag -eq $false) {
Try {
$web.DownloadString($url)
clear
Write-Host -ForegroundColor Green "$(Get-Date): Facebook is up!"
Start-Sleep -Seconds 30
## $flag = $True
}
Catch { Write-host -fore Red "$(Get-Date): Facebook is down..."
## email sending----------------
$emailFrom = "Halim@test.com"
# Use commas for multiple addresses
$emailTo = "Halim@test.com,halim1@test.com"
$subject = "Facebook May be Down(Test email notification system) !!"
$body = "Facebook May be Down. Please Check! (This is just a test email)" # Details: $($_.Exception)"
$smtpServer = "192.168.10.199" # your smtp server's IP or name.
$smtp = new-object Net.Mail.SmtpClient($smtpServer)
$smtp.Send($emailFrom, $emailTo, $subject, $body)
$flag = $True
##exit
## -----------------------
}
}
}
End {
Write-Host -fore yellow "Email send & This process need to run again for further monitoring"
}
How to execute or run :
1) Go to search or run and type “PowerShell”
enter
or go to the following exe, then
click
%SystemRoot%\system32\WindowsPowerShell\v1.0\powershell.exe
2)
Copy & paste the code on it, then enter.
