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


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

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

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

 Write-OutPut $h.GetCrawlHistory();


Then you can just execute: Get-CrawlHistory -url http://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.

    Hi There,

    Thanks for the sample. FYI, I tried but the CSV file is 0KB. Not sure what I miss or the requiremnt not met. Can you advice?
