Subject: about systemtap test!
Date: Sat, 25 Mar 2006 01:29:00 -0000 [thread overview]
Message-ID: <30c154100603241729s63ac1451i8b5d2de28a5ba831@mail.gmail.com> (raw)
Two problems:
1. I use the follow program for testing:
probe kernel.function("sys_open")
{
printf("%s(%d)open(%s)\n", execname(), pid(), argstr)
}
probe timer.ms(4000)
{
exit()
}
the result looks like this:
udev(10266) open()
udev(10266) open()
udev(10266) open()
nifd(1383) open()
...
So why have not anything include the open's parenttheses? And what
meaning of the "argstr"?
2. how use systemtap probes the watchpoint? Can you give me some examples?
thanks.
