How to determine memory used

[Glenn Couture]

I dont have root. How can I tell how much physical memory is being used. My sysadmin is clueless.

The numbers are not adding up. I know there is 4 gigs on the box..yet free and used dont add up to 4 gig.

Thanks for your reply

Hi:

# grep -i physical /var/adm/syslog/syslog.log

...will work if the log hasn't been trimmed.

Hello,
I dont think swapinfo will run without root acess. Top should do. Also you can run glance/gpm if installed on your system. Also you have vmstat.

Goodluck

Thanks for the help. I cant run swapinfo, the sysadmin let glance lisc. expire. The grep from the syslog did show memory at startup, but before oracle was running. Top info does not add up to 4 gig, but does show 2.5 gig free. Is it then safe to assume 1.5 gig used? Also vmstat does not add up to 4 gig.

Hi (again):

Oh, sorry, of course, 'syslog' shows physical memory not dynamic. No points for misreading the question please!

Hi Glenn

I am attaching a c program which i got from the forums yesterday. It is attached to the answer , just downlad it to the Pc , ftp it to the server. and then compile it using
( first rename the source from memuse.txt to memuse.c)

cc memuse.c -o memuse

change the permissions to 777 and run it as an excutable.

Nice program comes out witht the memory usage .

If you liked my memuse.c program, give this one a try.

cc memdetail.c -o memdetail
