dear all,
kindly i want to check my server memory utilization i used alot of commands but i want to make sure that it is acurate let me explain
i have a server which has 32GB RAM
Total Memory = 33423360 kb
Free Memory = 4172568 kb
Utilized Memory = 29250792 kb
Memory Utilization Percentage = 87.5 %
if Utilized Memory = 29250792 kb how can i make sure which processes eat this amount of memory
I listed the top proceses i found the following
i found also the swap device is free and not used my system now in test cycle and the memory reached to 87% i want to make sure that if it in the production it will still has 87% and use the swap space or exceed the amount of memory
i tested another server it has memory utilization like 46% and after rebooting it it was 29% so i want to make sure that how memory work it has some processes sleep in memory after we has a new instruction enterd the memory it will free some of the old processes ?

swap device
whem it will use free swap ?
free swap = 30375816k
used Swap = 4569504k
how come the amount of memory percentage in these processes that run by these users is equal to 7.4 % and the memory utilization is equal to 87%

forgive me for my weak english
ipcs -m
for shared memory usage may shed some light on things.
prstat for the whole system should show more than just a few users if it is an active system. What does
ps -ef
show?
