How to: Programmatically Export the Crawl History to a CSV File in PowerShell

  • 發行項

Hi,

When I came across the article at MSDN How to: Programmatically Export the Crawl History to a CSV File I thought I would never create such a tool just for that specific feature, as you end up with additional requirements in order to create an admin tool.

But today I needed to get data from crawl history, and I didn't want to get them from SQL (remember it is not supported ;)), so I started to write down a simple powershell script to do it. And then I realized that for this atomic actions, indeed it is a great options!: you give admin people multiple commands that they can use/combine to monitor/get information about the environment (and yes many, many things more)

## SharePoint Reference
[void][System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint")
[void][System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint.Administration")
[void][System.Reflection.Assembly]::LoadWithPartialName("Microsoft.Office.Server.Search.Administration")
[void][System.Reflection.Assembly]::LoadWithPartialName("Microsoft.Office.Server.Search")
[void][System.Reflection.Assembly]::LoadWithPartialName("Microsoft.Office.Server")

function global:Get-CrawlHistory($url)
{
 trap [Exception] {
  write-error $("ERROR: " + $_.Exception.GetType().FullName);
  write-error $("ERROR: " + $_.Exception.Message);
 
  continue;   
 }

 $s = new-Object Microsoft.SharePoint.SPSite($url);
 $c = [Microsoft.Office.Server.Search.Administration.SearchContext]::GetContext($s);
 $h = new-Object Microsoft.Office.Server.Search.Administration.CrawlHistory($c);

 Write-OutPut $h.GetCrawlHistory();

 $s.Dispose();
}

Then you can just execute: Get-CrawlHistory -url https://your_site_url/ | Export-Csv your_path_and_file_name

Then you can import to excel and make some charts.

In order to filter the information some useful columns should be denormalized: CrawlType, ContentSourceID, Status.

Cheers!

    This code only works for Sharepoint 2007. Has anyone been able to get crawl logs for Sharepoint 2010?
