I wrote a little powershell function that executes Get-EventLog against remote servers. On some servers this seems to just hang and never times out. Can I timeout a powershell function call? I see how to do this against a different process, but i want to do this for a power shell function.
thanks

function Get-Alert4
{
param($computer)
$ret = Get-EventLog application -after (get-date).addHours(-2) -computer $computer | select-string -inputobject{$_.message} -pattern "Some Error String" | select-object List
return $ret
} #
In Windows PowerShell 2.0, the default value of the IdleTimeout parameter is 240000 (4 minutes).
The Wait-Process cmdlet waits for one or more running processes to be stopped before accepting input. In the PowerShell console, this cmdlet suppresses the command prompt until the processes are stopped. You can specify a process by process name or process ID (PID), or pipe a process object to Wait-Process .
The most commonly used pause command is by far, Start-Sleep . This command takes two simple inputs, which are -Seconds and -Milliseconds . Seconds can be a System. Double number value while milliseconds takes only System.
You can implement timeouts by using a background job like so:
function Get-Alert4($computer, $timeout = 30)
{
$time = (Get-Date).AddHours(-2)
$job = Start-Job { param($c) Get-EventLog Application -CN $c -After $time |
Select-String "Some err string" -inputobject{$_.message} |
Select-Object List } -ArgumentList $computer
Wait-Job $job -Timeout $timeout
Stop-Job $job
Receive-Job $job
Remove-Job $job
}
