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:-

vm_stat
VM_STAT(1) BSD General Commands Manual VM_STAT(1)NAME
vm_stat -- show Mach virtual memory statistics
SYNOPSIS
vm_stat [[-c count] interval]
DESCRIPTION
vm_stat displays Mach virtual memory statistics. If the optional interval is specified, then vm_stat will display the statistics every
interval seconds. In this case, each line of output displays the change in each statistic (an interval count of 1 displays the values per
second). However, the first line of output following each banner displays the system-wide totals for each statistic. If a count is pro-
vided, the command will terminate after count intervals. The following values are displayed:
Pages free
the total number of free pages in the system.
Pages active
the total number of pages currently in use and pageable.
Pages inactive
the total number of pages on the inactive list.
Pages speculative
the total number of pages on the speculative list.
Pages throttled
the total number of pages on the throttled list (not wired but not pageable).
Pages wired down
the total number of pages wired down. That is, pages that cannot be paged out.
Pages purgeable
the total number of purgeable pages.
Translation faults
the number of times the "vm_fault" routine has been called.
Pages copy-on-write
the number of faults that caused a page to be copied (generally caused by copy-on-write faults).
Pages zero filled
the total number of pages that have been zero-filled on demand.
Pages reactivated
the total number of pages that have been moved from the inactive list to the active list (reactivated).
Pages purged
the total number of pages that have been purged.
File-backed pages
the total number of pages that are file-backed (non-swap)
Anonymous pages
the total number of pages that are anonymous
Uncompressed pages
the total number of pages (uncompressed) held within the compressor
Pages used by VM compressor:
the number of pages used to store compressed VM pages.
Pages decompressed
the total number of pages that have been decompressed by the VM compressor.
Pages compressed
the total number of pages that have been compressed by the VM compressor.
Pageins
the total number of requests for pages from a pager (such as the inode pager).
Pageouts
the total number of pages that have been paged out.
Swapins
the total number of compressed pages that have been swapped out to disk.
Swapouts
the total number of compressed pages that have been swapped back in from disk.
If interval is not specified, then vm_stat displays all accumulated statistics along with the page size.
