Memory Monitoring

[Ricky_2]

Hi, I'm trying to find out how much memory is consumed by a certain app so that I can port it over to another system. How can I get that figure over a period of time and how can I differentiate between those used by the code, data and stack? Thanks.

[RAC_1]

UNIX95= ps -ef -o "ppid,pid,vsz,args"|sort -nk3

this will give you sorted list of process depending on memory usage.

Here is one that is slightly different

UNIX95= ps -e -o user,pcpu,cpu,vsz,pid,ppid,args | sort -rnk2

Hi Anil, thanks for the advice. You see, I need to find out the total amount of memory resources being used by certain processes that were started by the app. vsz doesn't give a real picture because adding up the individual vsz values will give me a final value greater than my physical memory. Thanks.

Hi Harry, I'm not too familiar with glance but how do I grep the values over a period of time at certain intervals? Thanks.

These are purchasable products from HP. The data glance displays isn't really grep'able, that's why you use perfview to review the data that glance/measureware collects.

check the glance page for syntax.
you can exeecute the glance at regular intervals to check the memory usage.


check gbl_mem_util metric.

glance -adviser_only -j2 -iterations 2 -syntax ./glance.syntax >> /tmp/glance.mem

where glance.syntax file contains
print "GBL MEM UTIL ",gbl_mem_util line.

Hi everybody, thanks for the prompt responses. I'll try out your recommendations and let you know the outcome. Thanks again.

Ricky,
I used this command;
UNIXX95= ps -eo "vsz args" |sort -n |more.

Or you can Glance, all ways guide to Rome.
