Sysprof is a sampling profiler that uses a kernel module, sysprof-module.ko,
to generate stacktraces which are then interpreted by the userspace
program "sysprof".

See http://www.daimi.au.dk/~sandmann/sysprof/ for more information
See the Sysprof homepage:
- You need gtk+ 2.6.0 or better.
http://www.daimi.au.dk/~sandmann/sysprof/
- You need at least Linux 2.6.11
for more information
- The module must be compiled with the same compiler that compiled the
kernel it is going to be used with. For most systems that is just
the system compiler, but if you have upgraded your kernel it is
possible the one was compiled with a different compiler.
Please mail bug reports to
In that case, "insmod sysprof-module.ko" will produce this
Soren Sandmann (sandmann@daimi.au.dk)
Also information about whether it works or doesn't work on your distribution
would be appreciated.
Requirements:
- A Linux kernel version 2.6.11 or newer is required.
Unlike Sysprof 0.9, version 0.91 should work fine on SMP systems.
- GTK+ 2.6.0 or newer is required
Compiling:
- Sysprof must be compiled with the same compiler that compiled the
kernel it is going to be used with. Usually this is just the the
system compiler, but if you have upgraded your kernel it is
possible that the new kernel was compiled with a different compiler
In that case, "modprobe sysprof-module" will produce this
error message:
insmod: error inserting './sysprof-module.o': -1 Invalid module format
Debugging symbols
- The programs you want to profile should have debugging symbols, or
you won't get much usable information. On a Fedora Core system,
installing the relevant -debuginfo packages should do the trick.
installing the relevant -debuginfo package should be sufficient.
- To get usable data on the X server:
- X server.
The X server as shipped by most distributions uses its own home-rolled
module loading system and Sysprof has no way to deal with that, so if you
run sysprof with your normal X serverr you won't get any information about
how time is spent inside the X server.
To fix this you have to compile your own X server:
(1) Compile the X server to use ".so" modules:
- Uncomment the line "MakeDllModules Yes" in
xc/config/cf/xorgsite.def
xc/config/cf/xorgsite.def.
If you are compiling the CVS version of the X server
(the one that will eventually become 7.0), then this is
already the default.
- "make World"
