active memory - ok, but per process ?

active memory - ok, but per process ?

[devzero]

Hi, 

pardon - a user question, most likely for vm subsystem experts.
I`m searching for this for a while and don`t know any further.....

as we know  , 

cat /proc/meminfo |grep Active
Active:         139916 
kB

gives the " Memory that has been used more recently and usually not reclaimed unless absolutely necessary."

I wonder - isn`t there a way to break that down on a per-process basis ? (to see which process is the most active memory "consumer")

regards 
Roland

I'm not a vm subsystem experts, but maybe I can give my own comments.
Actually it's hard to maintenance per-process active pages. active
pages include many file page caches, not only per-process pages, these
caches don't belong to any process.(like some share library code
page).
So apparantly there have many common active mm through all process. is
this active mm number useful for you?
Maybe you can take some useful number like RSS & VSZ .(ps aux)
