Memory benchmarking tools

[Alex Macdonald]

I'm looking for information on tools for gathering memory performance numbers. Glance and top won't work for what I need, because I need to be able to access the information from the command line or a flat file from inside a perl script. I've looked at vmstat, but the nubers it's giving me really don't add up, or I just don't know how to read them.

I want to produce memory utilization numbers specifically, but any extra stats would help. Thanks in advance for your replies.

Check this out - called memdetail - got it from the forums here...:

# memdetail
Memory Stat total used avail %used
physical 10080.0 9737.5 342.5 97%
active virtual 9586.4 4655.6 4930.8 49%
active real 7257.5 3446.8 3810.7 47%
memory swap 7697.1 1664.7 6032.5 22%
device swap 26528.0 9298.5 17229.5 35%

Is that a standard tool, part of a package, or an open-source tool? I looked for memdetail on and HP-UX 11.0 and 11i box and I can't find it. Thanks!

Nevermind, I didn't see that it was attached. Thanks again!

Hi Alex,

See if you have Measureware installed "/opt/perf/bin/extract". If so, you can get good details on your memory stats with the following script.

Adjust FROM and TO and you will get stats during that time frame into a file called stats.out

#!/usr/bin/ksh

FROM=02/01/04
TO=02/04/04
LOG=stats.out

cat << EOF > /tmp/mwa$$
FORMAT ASCII
HEADINGS ON
SEPARATOR="|"

GBL_MEM_USER_UTIL
GBL_SWAP_SPACE_UTIL
GBL_MEM_PAGEOUT_RATE
GBL_MEM_SWAPOUT_RATE
TBL_BUFFER_CACHE_USED
GBL_MEM_QUEUE

EOF


/opt/perf/bin/extract -gG -r /tmp/mwa$$ -b $FROM -e $TO -xp -f $LOG

rm -f /tmp/mwa$$
