What program (under windows) do you recommend for monitoring the state of the network?

Question

Ping

There is a task to monitor the status of several computers on the network, in fact, it is necessary to monitor whether they respond to ping or not. If not, then report by mail or messenger which computer is unavailable.
I found a bunch of programs on this topic, but almost all are paid and all have very rich functionality.
Recommend free and simple.

Answer 1

Something like this, for example, if on powershell:
function NoPing
{
$From = "[email protected]"
$To = "[email protected]"
$SMTPServer = "smtp.email.ru"
$SMTPPort = "25"
$ Username = "[email protected]"
$Password = "password"
$subject = "server is down"
$body = Get-Date -Format "dd MMMM yyyy HH:mm:ss"
$message = New-Object System.Net .Mail.MailMessage $From, $To
$message.Subject = $subject
$message.IsBodyHTML = $true
$message.Body = $body
$smtp = New-Object System.Net.Mail.SmtpClient($SMTPServer, $SMTPPort)
# $smtp.EnableSSL = $true
$smtp.Credentials = New-Object System.Net.NetworkCredential($Username, $Password)
$smtp.Send($message)
}
if (test-Connection -ComputerName 8.8.8.8 -Count 2 -Quiet)
{
exit
}
else
{
NoPing
}

Answer 2

If for yourself then google 10 strike network monitor with a cure for greed. By all criteria, then fit.
In general, such software is usually not made under windows, because then who will monitor the monitoring? :)
If you still need it even simpler and under Windows there is a self-propelled gun that does almost what you need, if necessary I can finish it.
