Reporting on SharePoint Event Receivers

SharePoint Event Receiver Reporting

Event Receivers are a very powerful SharePoint construct. Because of timing issues, they can be tricky to get right. My good friend Jimil Ibrahim asked about this recently, prompting me to provide just such a reporting capability for general use. Below is a script that will quickly generate a report of all Event Receivers in all Libraries, in all SPWebs in all SPSites. The output is easily imported into MS-Excel for rapid analysis.

$wa=Get-SPWebApplication http ://SharePoint  #susbstitute with your own Web Application.

foreach ($site in $wa.Sites)
{
Write-Host "S" -NoNewline
	foreach ($web in $site.allwebs)
	{
	Write-Host "W" -NoNewline

		for ($LibIndex=0; $LibIndex -lt $web.Lists.Count; $LibIndex++)
		{
		Write-Host "L" -NoNewline
			$list = $Web.Lists[$LibIndex];

			$i=0;

			
			foreach ($ER in $list.EventReceivers)
			{
				Add-Content C:ReportsERs.csv "$($Site.url),$($web.title),$($web.url),$($List.title), Event $($i): $($ER.name), $($ER.Synchronization)"
				$i++
			}

		}
	}
}
