Automate ‘periodic daily’ e-mail reading
Many systems send status e-mails from their periodic {daily,weekly,monthly} cronjobs. But just as with log messages you probably stop reading them because there are too many mails (one or two mails per day and host) and they are very repetitious (on healthy systems they should not change too much). — This demands automation.
A simple solution is to eliminate variable fields from the periodic output and only send an e-mail if the output is different from the expected or the previous output.
