Activity Monitor
  Activity Monitor displays information about your processor,
  apps, disks, memory, and computer's network. You can use
  this information to determine what effect a process is
  having on performance and how much processor capability is
  being used. This information can be collected in a
  diagnostic report and sent to Apple Support to better help
  solve a problem.
