Error report In T30

I want to see error report in control panel error report page what can i do
Kindly Help me

I am not sure what you exactly want to do. There are different ways to get error reports:

Post-Mortem Debugging with Watson

On the Tegra Images we have post mortem debugging built in the image (since 2.0beta4). Thiss needs to be enabled. More details are located here.

Debugging serial port

Enable the deubg serial port as described here.

Debug message buffer

If you don’t have a debug serial port running and want to see what happend in the past, you can read out the debug message buffer. On Tegra this was added in the 2.1b2 image. There is a tool to read out this buffer See more details here.
