Usage

This library provide the following probe:

provider pystap {
  probe entry(char *, char *);
};

An easy decorator is implemented:

from pystap import dtrace_deco

@dtrace_deco
def its_a_test(a_para, that_para=None):
    print a_para, that_para

Example:

Usage is shown in test.py, execute bash command like following:

sudo stap  -e 'probe process.library("/home/vagrant/github/python-systemtap/libpystap.so").mark("entry"){printf("%s - %s", user_string($arg1), user_string($arg2))}'  -c "python test.py"

Note: You should manually give the location of libpystap.so to stap.
