I think i got it what the problem is.
it is showing delayed logs.
may it is writing in blocks.
waiting for buffer to fill and writing it whole at once.
this could be possibility.
tell me that if i am thinking correct or not.
if yes, is there any way to reduce the buffer size so that it could show 
the logs earlier.

Thank you
