awapinfo problem

[prasadb]

hello gurus,

I am giving here the o/p of 'swapinfo -tm'
my concern is that its showing 0% in used column, some application is facing problem on this server, its being down frequently, i want to know whether it is related to this memory issue..

# swapinfo -tm
Mb Mb Mb PCT START/ Mb
TYPE AVAIL USED FREE USED LIMIT RESERVE PRI NAME
dev 4096 0 4096 0% 0 - 1 /dev/vg00/lvol2
dev 4000 136 3864 3% 0 - 0 /dev/ibmvg01/swap
reserve - 1921 -1921
memory 2411 578 1833 24%
total 10507 2635 7872 25% - 0 -

You are only using 25% of all of your swap. There are no problems now, you will need to use that command when you have problems.

The 0% used for lvol2 means you haven't started swapping to that device but you have reserved 1.9 Gb, some there and some on swap.

Hi,

From the swapinfo o/p its clear that there is no issue in your server related to swapping.
And you can check the memory utilization in glance.

here are a couple of scripts I have come across from the ITRC. They are great.

Swap space is at 0% what that means is you never got close to using all of the memory so you never needed to swap. Since you have > 2 GB of memory unless you get to less than 64 MB of memory vhand does not start paging so you have lots of memory free. That is a good thing.
