Powershell - Tail Windows Event Log? Is it possible?

Question

How can i use powershell to tail a specific windows event log? Is it possible?

Answer 1

First, thank you Michael!

Slight refinement for my use case that includes showing the entire multi-line message value.

    function Get-WinEventTail($Provider="JobRequestQueueConsumerBackgroundService", $ShowExisting=10) {
    $formatProperty = @{ expression={$_.TimeCreated}; label="TimeCreated"}, 
                      @{ expression={$_.Message}; label="Message"; width=100}
    if ($ShowExisting -gt 0) {
        $data = Get-WinEvent -ProviderName $Provider -max $ShowExisting
        if ($data) { 
            $data | sort RecordId | Format-Table -Property $formatProperty -Wrap
            $idx = $data[0].RecordId
        }
    }
    else {
        $idx = (Get-WinEvent -ProviderName $Provider -max 1).RecordId
    }

    while ($true)
    {
        start-sleep -Seconds 1
        $idx2  = (Get-WinEvent -ProviderName $Provider -max 1).RecordId
        if ($idx2 -gt $idx) {
            Get-WinEvent -ProviderName $Provider -max ($idx2 - $idx) | sort RecordId | Format-Table -Property $formatProperty -Wrap
        }
        $idx = $idx2

        # Any key to terminate; does NOT work in PowerShell ISE!
        if ($Host.UI.RawUI.KeyAvailable) { return; }
    }
}

Get-WinEventTail

The -Wrap option was necessary to show a multi-line message, otherwise ellipsis would truncate the message at the end of the first line. Setting the column width did NOT help.
