Heres a little script to display bufcache size every 15 mins;

#!/bin/ksh
while true
do
DATESTAMP=`date +"%d-%m-%Y.%H:%M".%S`
CURRENT=`sysdef|grep bufpages|awk '{print $2}'`
(( BUF_IN_MB=(CURRENT*4) / 1024 ))
print "$BUF_IN_MB MB at $DATESTAMP"
sleep 15
done

Hi

Using sar

sar -b 10 100

Will collect every 10 seconds 100 times - see man sar.
