At work we use Icinga, and batch jobs submit passive results, if they fail or don't check in within a reasonable time, it triggers an alert. Probably more than you want to set up, but might give you some ideas. We have a wrapper script that sends the job status and output. Alternatively, you could make the jobs quiet on success and noisy on failure, and just have cron mail you about them? Or make a wrapper script that saves off the status and a status job that mails you if any failed?
