[arun khatwani]

I got request from client that are facing performance degrade in theor applications.

When we checked fouemd memory utilization is 97% utilized.

But when run the unix95 command did not find the Processes consuming high memory.

Glance X.04.73.121 12:27:22 htrxc1 ia64 Current Avg High

CPU Util SSU U | 13% 10% 15%
Disk Util | 0% 1% 1%
Mem Util S SU UF F | 97% 97% 97%
Networkil U UR R | 53% 53% 53%

Hi Arun,

You can use

UNIX95= ps -ef -o "vsz,pid,args" | sort -rn -k1 | head -n 5
*UNIX95= ps -e -o "user,pcpu,cpu,args" |sort -rn -k2 |head -n 5
*sar
*top
*glance -m
*swapinfo -tam

Thanks
Jitesh

support tool result:
kmeminfo

echo freemem/A | adb -o /stand/vmunix /dev/kmem

gives the freemem in hex on 11.31

How much memory do you have on the system.

97% of 16 gb is different that that of 96GB

Also you seem to have minimal CPU utilization.


May want to look at dbc_min and dbc_max or
filecache_max at 11.31
