Profiling daemon threads in Linux.. which tool?


From past few weeks, I have tried to profile daemons using following tools.
a. gprof - profiles only applications.
b. FunctionCheck - profiles threads but threads should exit.
c. AQtime - profiles only application and its threads not daemons.
d. Intel's VTune - profiles applications and its threads
I have no success using these tools
I have following flow in my project.

_____ ____ ____ ____
| app |----->| d1 |---->| d2 |----->| d3 |
| | | |<----| |<-----| |
| | | | ^^^ ^^^^
| | | |--->| d4 |
| | <--- | |<---| |
^^^^ ^^^ ^^^^

I need to profile daemon d4. Is there a tool which will profile
daemons launched by applications. Profile data
should include functions called by daemons, library functions, system functions, number of calls, time in micro seconds.

thanks in advance.
