I have just downloaded Xen-3.0.2 from website and install it on my Fedora 4
Linux system. The system can boot ok. Now I want to use Xenmon to monitor my
system. I use tools/xenmon. When I start xenmon.py, it reports "Failure to
get trace buffer pointer from Xen (22=invalid argument)". I check xenbaked.c
source file and find that tb_controls fail. I do not know how to do, if I
have to update xen or the Xenmon is not complete? If someone knows, please
help me!

If you installed Xen properly, you shouldn't have to go into tools/ to
run anything -- the binaries should be installed in the right places,
so you should be able to simply run 'xenmon.py'.

As Rob mentioned, you need to do:

$ tbctl 1                  # this turns tracing on
$ setsize 20               # size of trace buffers
