hi Dan,
   try callgrind [http://kcachegrind.sourceforge.net].
   callgrind will give you the info about time spent for each
instruction/function , but you cannot log anything.
fedora has callgrind and valgrind  by default.
just compile your program with debug info (-ggdb) and run it with
callgrind. (or valgrind --tool=cachegrind).
do the following ::
1) compile with debug info,
2) callgrind --trace-jump=yes --dump-instr=yes <program_name> <args>
3)you will get a file in cur dir , something like  callgrind.out.<pid>
4)kcachegrind callgrind.out.<pid>

in kcachegrind , you can view the time that was spent in each function.
it will display the call graph as well , but for that you need the dot
utilty, which can be obtained from http://graphviz.org.

hope this helps,
cheers,
vineeth.
