Linux IA64, How to find how much memory is consumed by linux kernel

KRUPASINDHU PRADHAN — Sat, 15 Nov 2008 06:02:48 GMT

Hi,
I have a simple question.

Linux Node1 2.6.10-telco-1.46-mckinley-smp #1 SMP Fri May 30 18:29:43 UTC 2008 ia64 GNU/Linux

1. How to determine what is the total amount of kernel memory consumed in my IA64 LINUX System ?

2. How to determine per process level how much kernel memory is consumed(or it does make sense as kernel works for all process , and there would mutual memory used for all process)

Probably, you should take a look to /proc/meminfo, free and pmem:

Hi,
"top" command will provide you information about the process and resource consumed by them such as mem, cpu-time etc..
Cheers...!

# vmstat

# cat /proc/meminfo

# top

# free -m

with "ps -eo rssize,vsize,command"

- rssize = physical memory that a task has used (in kiloBytes)
- vsize = virtual memory size of the process in KiB (1024-byte units)
- command = process

example for the 10 highest physical memory processes: ps -eo rssize,vsize,command | sort -n | tail -10
