$ man sar

-B     Report paging statistics.  The following values are displayed:


          pgpgin/s
                 Total number of kilobytes the system paged in from disk per second.

          pgpgout/s
                 Total number of kilobytes the system paged out to disk per second.

          fault/s
                 Number of page faults (major + minor) made by the system per second.
                 This is not a count of page faults that generate I/O, because some page 
                 faults can be resolved without I/O.

          majflt/s
                 Number of major faults the system has made per second, those which have 
                 required loading a memory page from disk.

          pgfree/s
                 Number of pages placed on the free list by the system per second.

          pgscank/s
                 Number of pages scanned by the kswapd daemon per second.

          pgscand/s
                 Number of pages scanned directly per second.
