tapset::signal(3) systemtap signal tapset

DESCRIPTION


  This family of probe points is used to probe signal activities.
  Since there are so many signals sent to processes at any given
  point, it is advisable to filter the information according to the
  requirements.  For example, filter only for a particular signal
  (if sig==2) or for a particular process (if pid_name==stap).
