Installing

sudo apt-get install systemtap linux-image-`uname -r`-dbg linux-headers-`uname -r`

Additionally, the systemtap-doc package contains manpages for the probes, which is really nice, so you might want to install that as well.

Oneliners

Listing syscalls:

For example, all open syscalls:

stap -e 'probe syscall.open { printf("%s(%d)\n", execname(), pid()) }'

Or replace open with * and see everything. For example:

stap -e 'probe syscall.* { if (execname() != "stapio") printf("%s(%d) -> %s\n", execname(), pid(), probefunc()) }'
