Powershell script to Enable Developer Dashboard

Here is the Powershell script to Enable Developer Dashboard in SharePoint 2010

Add-PsSnapin Microsoft.SharePoint.PowerShell
[void][System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint")
[void][System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint.Administration")

##Turn On: for on-Demand Mode

$service = [Microsoft.SharePoint.Administration.SPWebService]::ContentService
$addsetting =$service.DeveloperDashboardSettings
$addsetting.DisplayLevel = [Microsoft.SharePoint.Administration.SPDeveloperDashboardLevel]::OnDemand
$addsetting.Update()

##Turn On

$service = [Microsoft.SharePoint.Administration.SPWebService]::ContentService
$addsetting =$service.DeveloperDashboardSettings
$addsetting.DisplayLevel = [Microsoft.SharePoint.Administration.SPDeveloperDashboardLevel]::On
$addsetting.Update()

##Turn Off

$service = [Microsoft.SharePoint.Administration.SPWebService]::ContentService
$addsetting =$service.DeveloperDashboardSettings
$addsetting.DisplayLevel = [Microsoft.SharePoint.Administration.SPDeveloperDashboardLevel]::Off
$addsetting.Update()

Mode of developer dashboard:

On – creates everytime the output at the end of the page content

Off – switch off developer dashboard and nothing is rendered

OnDemand – creates a DeveloperDashboard icon to make dashboard output visible as needed

Developer Dashboard is visible on the upper right hand corner:
