Welcome to the  group.

For this case, I need to execute application from shell or in a batch mode.

You can run MOOSE simulations without the GUI. Read the documentations.

You can compile it with profiling support. You need to look at the Makefile
and edit it. I am not aware of any specific profiling mechanism built into
MOOSE. Valgrind works, but it may be prohibitively slow. A simulation is
executed by the start() function [ interfaced to shell/Shell.cpp:
Shell::doStart(...) ]. Again, you can get better idea by first reading the
documentation and then reading the code. You can use gdb (with a
debug-build of MOOSE) to step through the code to some extent and
understand how it works. One warning though, do not use debug builds of
Python, the PyMOOSE interface will fail with an assertion error in the
Python interpreter.

Best,
