Hi Bijoy,

"Memory" used by a process is an abstract term as HP-UX implements demand paging.

Looks like you have already configured the httpd processes as an 'application' in measureware. If so, you can get the stats using the 'extract' command on 'APPLICATION' metrics.

APP_MEM_RES
APP_MEM_UTIL
APP_MEM_VIRT

The above will give you enough information on memory usage of your 'application'.

If you don't have it, then the best bet is to use the 'ps' command to sum up. For ex.,

UNIX95= ps -C httpd -o 'vsz' |awk '{ sum += $1 } END {print sum/1024}'

Should give you the resident memory in MB of httpd processes.
