And, if that's not enough, the OP can
  /sbin/swapon -s
or
  cat /proc/swaps
to get more info (both report the same info)

  ~ $ /sbin/swapon -s
  Filename                        Type            Size    Used    Priority
  /dev/sda3                       partition       31471328        1180    -1

  ~ $ cat /proc/swaps
  Filename                        Type            Size    Used    Priority
  /dev/sda3                       partition       31471328        1180    -1
