Thanks for your answer.
 There are several reasons why I dont want to do it that manner:
1 If we ever change the way passive updates are done we would have to change each and any of the jobs.
2 Many of the jobs are like this
echo "update a set b=c where d " | mysql
and I cant figure out how to add there a passive update to notify OK or failure ...
3 I want to be able to group my jobs by service and be able to modify this without having to go
through each and any of the jobs
4 There are dozens of cron jobs and maintained by different people. Having to add monitoring to each
of them is far more effort than providing a generic solution based on standard return status and stderr generated by the jobs
