LTTng vs OProfile

I am working on developing a toolbox for one of our embedded products (ARM Cortex-A8). Some of the tools I've looked at are LTTng, OProfile, and Valgrind. Can someone briefly describe the differences between LTTng and OProfile? I am trying to determine if our toolbox should include OProfile or not.

Thank.

There is actually another choice called perf that is integrated into the kernel source. I think this is a good replacement for OProfile.



See the primary wiki for more details. here
