When its over 100% do the following actions

Question

Hello,
We have a following script.
Purpose of this script is to received email notifications when FS /opt is over 90%.
PCT_USED=$(df -k /opt | tail -1 | awk '{print $4}' | sed 's/%//')
echo "Info:PCT_USED:[$PCT_USED]"
MY_THRESHOLD=90
if [ $PCT_USED -gt $MY_THRESHOLD ]; then
mail -s "/opt is Over 90% in TestNode 1" [email protected] < /home/oracle/FSwatch.log
mail -s "New Changes to the FS in Test Node 1" [email protected] < /home/oracle/NewFile.log
mail -s "Here are the Large files over 100MB from Test Node1" [email protected]
< /home/oracle/LargeFile.log
echo "Info:Sending Mail"
else
echo "Info: Usage [$PCT_USED] not greater than [$MY_THRESHOLD]"
fi
We get values from the cron job as below:
30 6,14,22 * * * ( date ; df -h / /opt /tmp /dev /bkup /var /usr /opt/oracle/clearcase_release /var/vobstore /wcmsrch) >> /home/Oracle/FSwatch.log 2>&1
45 6,14,22 * * * ( date ; find /opt -mtime -1 -ls ) >> /home/Oracle/NewFile.log 2>&1
50 6,14,22 * * * ( date ; find /opt -size +100000k ) >> /home/Oracle/LargeFile.log 2>&1
00 7,15,23 * * * /home/Oracle/callover90
Now I would like to add logic when its over 100% do the following actions.
1) send message to the users to contact system administrator
2) remove /opt/oracle/headdump/javacore (remove all javacore files)
How to add this logic?

Answer 1

I have added following logic in our existing program to find FS size, new files, size over certain numbers:
mail -s "Action1:Please remove javacore files" [email protected]< /home/oracle/action1
mail -s "Action 2:Please contact System Administrator" [email protected]< /home/oracle/action2
# more action1
Please remove javacore files from /opt/oracle/AppServer/profiles/AppSrv01
#Here is the command to remove all javacore files from the System, cd to above p
ath and run the command as
# rm javacore*
#more action2
Please contact System Administrator for further assistance
Do u have any better thought?
