Online memory utilisation

[Kasman_1]

Hi Gurus,

Is there any program/script that i can use for online monitoring of HP-UX memory utilisation ?

Thanks !

Hi Kasman,

Several commands you can use, depends on what you prefer:

top, but not too much info
glance, if you have installed that
swapinfo -tam, to check your swap memory

I prefer to use glance, but it need to be installed first. If you want to check if you memory is still ok, you can use:
cstm
cstm> map
cstm> sel d
cstm> info
cstm> wait
cstm> il
cstm> exit

Hope that will do, best regards,

Peter.

Hi,

If you want to see the processes on the top of memory usage, try the following:
TRHLD=1000
ps -el |sort -nr -k 10,11 |awk '$3 !="UID" {s+=$10;if($10>trh)print}
END{printf("%d PAGES %d MB\n",s,s/dv)} ' trh=$TRHLD dv=256

This command shows processes which use more than 1000 pages of memory.

Good luck

Hi,

If you are talking also about virtual memory, you can use vmstat. For example:

#vmstat -dnS 5 1000
