powershell alert when ping time drops

Hi guys, we have a switching mechanism on our servers whereby the networks switch speeds varying on location. These times can vary but is it possible to email when the ping time drops, which would indicate the network switch. I have the following script below but doesnt seem to work correctly. also is it possible to loop until the condition is met

thanks


$ping = ping server
if ($ping -gt 1000)
{
Send-MailMessage -To user@company.com -From "user@company.com" -SmtpServer smtp.domain.com -Subject "Ready"
}

Using this snippet:
$Comp = "localhost"
$ping = get-wmiobject -Query "select * from win32_pingstatus where Address='$comp'"

You should be able to do a simple check against ping time:

if ($ping.responsetime -gt 1000)
{
//Do something
}

HTH,

"Ping time drops" - does that mean the time is greater or less than a limit? Your code fragment would trigger if the time needed for a ping is more than 1 second.
$Ping = Test-Connection -Count 1 -TTL 2000 -EA SilentlyContinue Server
if (!$Ping -or $Ping.ResponseTime -gt 1000)
{
  Send-MailMessage -To user@company.com -From "user@company.com" -SmtpServer smtp.domain.com -Subject "Ready"
}

Open in new window

which will also trigger if the target does not answer.

Hi guys, when its on one network it's ~ 800 ms and then on VPN  < 100.  Qlemo i changed it to less than 100 but it doesnt loop until this condition is met. can this contiunually loop until that condition is met?

thanks

'f course it is, but you didn't say that yet ;-)
while (!($Ping = Test-Connection -Count 1 -TTL 2000 -EA SilentlyContinue Server)
   -or $Ping.ResponseTime -gt 100)
{
  Start-Sleep -seconds 60
}
Send-MailMessage -To user@company.com -From "user@company.com" -SmtpServer smtp.domain.com -Subject "Ready"

Open in new window

This will scan once every minute, until ping time is less or equal 100.
