Monitoring files

[adamsd]

Hello,

I have Big brother up and runnign and it monitors filesystems. Does anyone know if there is a way to monitor file sizes, we have a database file with a limitation upto 2Gb and if it goes beyond that our application crashes. I would like to monitor this file for growth.

Please HELP!!!!

Cheers
Dexter

Hi,

There may be a nice package for doing this but as I'm only a script hacker:

An easy way to do it would be to stick the following in a script called by crontab with a line like

0,20,40 * * * * /scriptpath/script # run script every 20 mins

This script can be varied for different thresholds and or MAX file sizes and e-mail users by changing the constants. It obviously only works if you have setup mail on the aix box.



# define constants
MAXFILE=2147483648 #2gigabytes
ALARM_THRESHOLD=90 #percentage above which you want a warning
MAIL2="root sysadmin dbadmin" #add any users you want
#
FILE=/path/DB_FILE #whatever the path to your DB file
FILESIZE=$(ls -al $FILE | awk '{print $5}')
FILE_BY_100=`expr 100 \* $FILESIZE`
PERCENT=`expr $FILE_BY_100 / $MAXFILE`
#
if [ $PERCENT -gt $ALARM_THRESHOLD ]
then
echo "$FILE has gone above warning threshold, please take action" | mail -s "$FILE too big" $MAIL2
