Comment 14 for bug 429257

That is what I get:

udevadm monitor -e --udev 2>&1 | tee /tmp/udev.log
^C
root@norbert-laptop:~# ls -l /tmp/udev.log
-rw-r--r-- 1 root root 0 2009-11-18 19:58 /tmp/udev.log

udevadm monitor without further parameters:
udevadm monitor
monitor will print the received events for:
UDEV - the event which udev sends out after rule processing
KERNEL - the kernel uevent
