PowerShell script for creation of Custom Event Source and Event Log

Copy the PowerShell script below and save it as EventSourceCreation.ps1 for creation of Event Source and Event Log:

#Write-Host "Remove event source SharePointEventSource"
Remove-EventLog -Source SharePointEventSource
#Write-Host "SharePointEventSource removed"

#Write-Host "Create event source SharePointEventSource"
New-EventLog -LogName "SharePoint Event Source" -Source SharePointEventSource
#Write-Host "Event source SharePointEventSource created"

Once event source has been created, go to Run => eventvwr and you will see that the new
"SharePoint Event Source" has be created under the Application and Services Logs, see snapshot below:

To automatically run the above script as a batch utility, copy and paste the code below and save it as a .bat file extension:

cd /d %~dp0
powershell -noexit -file ".EventSourceCreation.ps1" "%CD%"
pause

Can write custom logging in SharePoint using the SPDiagnosticsService class to log messages and exceptions against the above custom source created namely: SharePointEventSource

Run the script and enjoy :)
