How to create a script that will email once there is an error?
Hi Guys,

Good day ULF! Can you assist me in creating a script that will email once an error has occurred. It's like this, I have script that is used for monitoring, distinct keywords on the status are OK and Error respectively. Then I created another script that will call for the monitoring script to run so that the new script will save an output into a file. I call it as Status-Collector.sh and I will put it as an entry in cron. This is the sample output that has been generated:
Code:
Date Executed:
--------------
Thu Dec 22 13:30:54 EET 2011


Command Executed: <command-01>
------------------------------------------------------
SNMP Status = OK

Command Executed: <command-02>
--------------------------------------------------------
SYSTEM Status = OK

Command Executed: <command-03>
-----------------------------------------
DISKSPACE Status = OK

Command Executed: <command-04>
-------------------------------------------------------
TOTAL_USER Status = OK

Command Executed: <command-05>
---------------------------------------------------------------
VR_ROLE Status = OK

Command Executed: <command-06>
server0
--------------------------------------------------------------------------------
RDVR_ROLE Status = OK

Command Executed: <command-07>
------------------------------------------------------
SERVER_BOOT Status = OK

Command Executed: <command-08>
------------------------------------------------------------------------
RDSERVER_BOOT Status = OK

Command Executed: <command-09>
------------------------------------------------------
Error! High Load Average = 1.10 in server8 for the last 5-minutes.

NOTE: Logs can be found in /tmp directory with file extension name of .debug

I want a script that will read per line of the output file and will email if one or more Errors occurred.


Please advice,

BTW: I would like to personally thank Unix and Linux Forum, my respect and appreciation to all the members and "staffs" of this. I myself admit that I'm learning a lot each day. Thank you so much, keep-up the great work. God bless!

Hi,

if I understood your post, the monitoring script logs an error message if an error condition is met.
why don't you make the monitoring script to also return an exit code other than 0 when the error condition occurs, so that the first script (that is, the script that calls the monitoring script) can just check the exit code of the second script and decide if sending an alert email is necessary or not? This way, the first script doesn't have to check for error entries in the log file.

see ya

Maybe you can try something like this,

read the output file containing logs

grep *Status = Error O/p Log file >temp_mail_file

then send mail containing body as temp_mail_file
with
/usr/lib/sendmail -t -oi <temp_mail_file

This will work in UNIX AIX version
