Developer dashboard sharepoint 2010

Developer dashboard
Make sure to copy the stsadm to under the c:
C:>stsadm -o getproperty -pn developer-dashboard
C:>Stsadm –o setproperty –pn developer-dashboard –pv ondemand

The you will find a new icon beside the logon name in central admin

To disable the option or enable it
Stsadm –o setproperty –pn developer-dashboard –pv Off
 To display the additional diagnostic information all the time, you use the same com­mands, but instead of specifying ondemand as the developer dashboard type, you provide a command to create an on/off icon that enables and disables the dashboard as needed.
You use the icon to toggle between displaying and hiding additional detailed diag­nostics.
