how to check ram usage by process

christopher_c · 04-30-2008, 01:10 PM

Hey guys

I was wondering if there was a command that would be able to show me the amount of ram that each process is consuming. Also, after using the command cat /proc/meminfo, I get the following:

MemTotal: 262316 kB
MemFree: 3176 kB

Im assuming 3000kB is VERY low right?

Hi,

'top' or 'ps'

You can 'man' to get the specifics.

MemFree shows you takes into account all disk caches and buffers together with actual programms memory. To count memory occupied by programs you should subtract MemFree Buffers and Cached from MemTotal.
