I am new to AIX, Can someone please help me how to know the swap space, total physical memory and system cache?
man pages will tell you that - the commands necessary to find it out, that is.
Code:
man -k paging
for instance, will list the following:
Code:
# man -k paging
chps(1) - Changes theattributes of a paging space.
lsps(1) - Displays thecharacteristics of a paging space.
mkps(1) - Adds an additionalpaging space.
rmps(1) - Removes aninactive paging space.
swap(1) - Provides a paging space administrativeinterface.
swapoff(1) - Deactivates one or more pagingspaces.
swapon(1) - Activates apaging space.
Now try man lsps and you will soon be guided to lsps -a, which displays everything you probably want to know about your swap(s):
Code:
# lsps -a
Page Space Physical Volume Volume Group Size %Used Active Auto Type Chksum
hd6 hdisk0 rootvg 16384MB 1 yes yes lv 0
To get the attributes of a device - like the memory - you sue the "lsattr" utility in AIX. Here is one of my systems (AME factor 1.2):
Code:
# lsattr -El mem0
ent_mem_cap I/O memory entitlement in Kbytes False
goodsize 3328 Amount of usable physical memory in Mbytes False
mem_exp_factor 1.20 Memory expansion factor False
size 3328 Total amount of physical memory in Mbytes False
var_mem_weight Variable memory capacity weight False
What you do mean with "system cache" is not clear. If you want to know the current amount of memory dedicated to the file cache issue vmstat -v and look for the "numperm" value. This is the percentage of real memory used for file caching right now. The value may change any time.
If you want to use more about how and why this value changes i suggest you search this forum for "memory utilization", but i can wholeheartedly suggest this thread as a starter. If you have specific questions, just check back.
Hi All,
We have a sparc server for which we always recieve memory utilization alerts. (97.01% available memory used by the partition (/MEMORY/MEMORY/MEMUsedMemPerc)).
But when we check the server using prstat and vmstat the meory utilization is normal and swap space utilization is also normal.... (1 Reply)
I am constantly getting request to run reports on our AIX server for system health (cpu, io, memory, etc) when users experience performance issues. We are using SolarWinds to monitor system health and it works great for cpu and disk space; however, I cant seem to get memory and io to work... (5 Replies)
