Hi,
we use PRTG, but this is a Windows program and use Powershell/Batch/VBScript.
For Powershell it looks like this:
Call SCRIPT.ps1 <FARMNAME> server
-----------------------------------------------------------------
-----------------------------------------------------------------
$username = 'XXX'
$password = 'XXX'
$zen1 = "IP ZEN 1"
$zen2 = "IP ZEN 2"
if($args.Length -eq 2){
$farm = $args[0]
$checktyp = $args[1]
}
if($checktyp -ne "session" -and $checktyp -ne "server" -and $checktyp -ne
"master") {
$x = [string]-1 + ":Falscher checktyp!"
write-host $x
exit 2
}

Betreff: [Zenloadbalancer-support] Magios monitoring
Hi everybody,
When you install a ZEN load balancer cluster, you know that if one server
fails the other server will take care of everything.
But I want to know if there is any way to check that both servers are alive and
working by using Nagios.
I mean, if one server is down due to a failiure and the other server fails,
then there are no more servers to keep the system online. So, how can I use
Nagios to know that one server is working and the other one is monitoring the
first one?
Thank you very much!
