I might be wrong but I see a flaw in your contrôl.

Your contrôl is based on this check :

Code:

if [ $INCEPT -gt 0 ]

$INCEPT being the value of your watched log_file. What happens if the process who feeds your log file crashs? Or if the application fucks up and don't have anything else to feed to your log_file?

Your log file will still be greater than 0 and your script won't detect it.

I was thinking of a similar script for work with the same check on a log file (ls -lrt | awk '{print $5}' )
but instead of checking the current value, I compare the new value to the previous one (just by redirecting old value to random file > old_value) and if it's equal to the previous value => restart.

Something like this

Code:

NEW_VALUE=`ls -lrt $LOG_FILE |awk '{print $5}'`
OLD_VALUE=$(cat /filesystem/scripts/old_value)

if [ $NEW_VALUE = $OLD_VALUE ]
   then
          echo "bla bla, not working"
          # restart process
   else
          echo "Log check ok, incrementing"
          $NEW_VALUE > "/filesystem/scripts/old_value"
fi

Might need a little tweaking or add a count so that it only restarts the process after 2 failed checks or something.


Just an idea anyway.
