How to log an eventlog only when the script gives a red error?

what i want to do is - log an event in the eventlog - application, only when the scheduled script gives any red error in that session...

I know how to log it with Write-EventLog, but cant limit it to only when it gives a red error saying something maybe wrong.

your response is much appreciated!

One way is to clear $Error before your statemtent, then check if an error occurred:

$Error.Clear()
Invoke-Something
if ($Error.Count -gt 0) {
  Write-EventLog ...
}

Or you could turn all errors into terminating errors and use a try..catch statement:

$eap = $ErrorActionPreference
$ErrorActionPreference = 'Stop'
try {
  Invoke-Something
} catch {
  Write-EventLog ...
}
$ErrorActionPreference = $eap
