How to write custom logs into ULS logs – SharePoint Foundation 2010 ( WSS 4.0) ?

  • [アーティクル]

Here is a sample script for writing your custom entries into ULS log. In WSS 3.0 it was little difficult as there was no any direct APIs to do it like in MOSS. But in 2010 version, SharePoint Foundation (WSS 4.0) also has this facility.

C#

 using System;
 using System.Collections.Generic;
 using System.Linq;
 using System.Text;
 using Microsoft.SharePoint.Administration;
  
 namespace WriteIntoULSLog
 {
     public class Program
     {
         public static void Main(string[] args)
         {
              
             SPDiagnosticsService diagSvc = SPDiagnosticsService.Local;
             diagSvc.WriteTrace( 0, 
                                                     new SPDiagnosticsCategory("Sowmyan's category",  TraceSeverity.Monitorable, EventSeverity.Error), 
                                                     TraceSeverity.Monitorable,
                                                     "Writing to the ULS log:  {0}",
                                                     new object[] { "SharePoint 2010 rocks!"});           
             
   
         }
     }
 }

PowerShell

 $diagSvc = [Microsoft.SharePoint.Administration.SPDiagnosticsServices]::Local
 $category = new-object Microsoft.SharePoint.Administration.SPDiagnosticsCategory(“My Category”,
                                    [Microsoft.SharePoint.Administration.TraceSeverity]::Monitorable,
                                   [Microsoft.SharePoint.Administration.EventSeverity]::Error )
 $diagSvc.WriteTrace(0, $category, [Microsoft.SharePoint.Administration.TraceSeverity]::Monitorable, “Write your log here” )

    Ah! It would have helped had I used WriteTrace instead of WriteEvent... Works great, Thx!

    An excellent, unit-test-friendly way to log to the ULS is by using the SharePoint Guidance Library: http://spg.codeplex.com/ It includes Full-Trust proxies to facilitate logging from Sandbox solutions. Chris

    This will just only log the custom string into defined area.When you need to customise areas then http://spg.codeplex.com is the only one way. Just follow there!

    The above code will throw security exception unless executed under SPSecurity.RunWithElevatedPrivileges() method.
