Hi all,
I am happily using sk_stream_wait_memory.stp sample program from the
systemtap website to track the occurrences of TCP send calls by an
application that are blocking on full send buffers.
What I would like to do know is also print out the size of the send buffer
that is full at the time of the blocking. I belive the kernel dynamically
adjusts the size of the send buffer.
Does any one have any tips or pointers on where to start looking to create a
probe that could get this info?
Cheers,
Ivan
