[Bug 27441] Re: Thrashing hell

[Colin King]

Hi,

Here is a simple shell script that will monitor you system's activities
into two log files, vmstat.log and top.log.  It will by default run for
600 seconds, but one can specify the number of seconds to run for if
required. This can possible help you track down the rogue memory hogger.

vmstat.log will show you the general overview of system activity. 
top.log will show per-process activity

#!/bin/sh  
vmstat 1 > vmstat.log &
vmstatpid=$!
top -b -d 1 > top.log &
toppid=$!
if [ x$1 = x ]
then
        secs=600
else
        secs=$1
fi
sleep $secs
echo $vmstatpid $toppid
kill -KILL $vmstatpid
kill -KILL $toppid
