How to write unix script for vmstat
- Thread starter narri
- Start date
**Korn Shell
LOOPCT=0
vmstat 600 |& # coprocess resample every 10 minutes
while read -p # while the coprocess if running
do
echo $REPLY
LOOPCT=$(($LOOPCT+1))
if [$LOOPCT -gt "50"
then
exit 0
fi
done
If you alter the loop count and vmstat seconds you can collect data for weeks at a time. This works the same for other similar utilities like netstat, etc. The first data line in the file should be disregarded as it is cumulative since the machine was rebooted.
