title: How to monitor number of syscalls executed by kernel?
body: <p>I need to monitor amount of system calls executed by Linux.
  I'm aware that vmstat has ability to show this for BSD and AIX systems, but for Linux it can't (according to man page).</p>
  
  <p>Is there any counter in <code>/proc</code>? Or is there any other way to monitor it?</p>
