Memory status

UNIX AIX

hi,

how to checck memory and paging utilization in mb in aix 6.1

vmstat output is not clear

thanks to all

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).

try

nmon

command it's really useful

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

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.
