If it is a formatting problem I recommend "vmstat -w". This works better for larger screens (like a remote session).

If it is a understanding problem I recommend two things: using something like topas (this may help: Introduction to topas), and reading up on VMM on Unix (try this: Overview of AIX page replacement).

nmon

The topas command is real useful for monitoring it. Run "topas" and look near the right side, you'll see something like this:

Code:
PAGING           MEMORY
Faults       12  Real,MB    2048
Steals     1972  % Comp     93.5
PgspIn        0  % Noncomp   5.2
PgspOut       0  % Client    5.2
PageIn        0
PageOut    2016  PAGING SPACE
Sios       2016  Size,MB    4096
                 % Used     31.8
NFS (calls/sec)  % Free     68.1

Note, this does not write to a file so you can't use this for historical recordings. Using nmon, like Vit0_Corleone said, would do that for you.
