Script for validation


I need a script which do below

I have one process which runs 24*7 daily and I always has to monitor it now i want to have this automated such that if it stops at anytime we get a exception mail.

For example i use ps -ef|grep 'etl'
above command gives me the desired output.

What i am thinking is like to run this script using cron which will run in evry 5 minutes.

So i need a validation script which works like if my process stops it will throw an exception via mail and will be able to start it immediately.

Please advise.

Many thanks in advance

I would try this:
ps -ef | grep test | grep -v grep
if [ $?==1 ] then; echo "test does not work" |mail -s "confirmation"; fi

But I am sure there is more elegant way Smilie

Hi Thanks for the suggestion.

I would try this. Meanwhile could you please help me in understand the command you use below

ps -ef | grep test | grep -v grep

ps - ef

- lists processes
grep test

- print output lines that contain "test"
grep -v grep

- excludes the "grep test" process you ran earlier from the list

: syntax error at line 5: `fi' unexpected

Your script should look something like this :


#Get the number of processes containing etl running
VAR=`ps -ef | grep 'etl' | grep -v grep | wc -l`

#Verify if VAR >= 1
if [ $VAR -lt 1 ]; then
        echo "Problem -  No etl process running" | mail -s "No process Alert"
