When it comes to monitoring your systems and applications, you'll soon start to look at email notifications to help you get alerts whenever issues are occurring. These types of email alerts are generally configured under an administrator email account or similar within the specific application where all emails go through.
Depending on the complexity of your systems and technologies, these types of email notification configurations may be straightforward via a graphical user interface (GUI), or you may be digging around at the command line using the console to configure specific packages to send out email notifications. One of the most important things though, beyond the configuration, is that you need to be able to view information about what has happened off the back of an email being sent by the system.
