To get the total memory simply look for its attributes:
lsattr -El mem0
What exactly do you mean by "total memory" and "free memory"? The available physical RAM? The available space in RAM plus the available swap space (the virtual memory) ? Depending on what exactly you want to know you can use vmstat or svmon (only as root) with various options. You can also use topas, nmon or any other similar tool, because the numbers they show are available on public OS interfaces (read: system calls) which are just queried by these tools. The difference to svmon and vmstat is just the presentation of the data gathered this way.
You can also use "vmstat -v", just keep in mind that the number is shown in memory pages (in AIX this is 4k) instead of bytes or kilobytes. For example, a machine with 16GB RAM installed (i have marked bold the corresponding numbers for you):

good morning,
how I can know how much total and free memory I have in my AIX 5.3 server, and this is shown in megabytes or gigabytes?
Thank you very much. (4 Replies)
Hi Experts, need some help.
I`m trying to write a shell script to get free, used and total memory on our linux servers.
It's working great, but i need follow some standards to make it a real nagios plugin.
It's pretty simple, you just type two parameters to the script, check_ram -w 80 -c 90... (4 Replies)

Hi,
Below is the code snippet I use on Linux (Centos) to retrieve the Process Name, PID and memory consumed on Linux (Centos) host:-

sg_get_swap_stats
sg_get_mem_stats(3) Library Functions Manual sg_get_mem_stats(3)NAME
sg_get_mem_stats, sg_get_swap_stats - get VM statistics
SYNOPSIS
#include <statgrab.h>
sg_mem_stats *sg_get_mem_stats(void);
sg_swap_stats *sg_get_swap_stats(void);
DESCRIPTION
Memory statistics are accessed through the sg_get_mem_stats function. It returns a pointer to a static sg_mem_stats.
The sg_get_swap_stats returns returns swap statistics. It returns a pointer to a static sg_swap_stats.
On the FreeBSD operating system elevated privileges are required to access the swap statistics. Making the program setgid kmem should be
sufficient. Programs running as root will not have this problem.
RETURN VALUES
The VM system calls can return a pointer to either a sg_mem_stats or a sg_swap_stats.
typedef struct{
long long total;
long long free;
long long used;
long long cache;
}sg_mem_stats;
total The total amount of memory in bytes.
free The total free memory in bytes.
used The total used memory in bytes.
cache The amount of cache used in bytes.
typedef struct{
long long total;
long long used;
long long free;
}sg_swap_stats;
total The total swap space in bytes.
used The used swap in bytes.
free The free swap in bytes.
TODO
Add a function to hold open the file descriptor to the kernel memory structures. Doing this would allow the elevated privileges to be
dropped early on.
