The CheckSystem notification system sends an alert e-mail if one of your specified limit has been exceeded. CheckSystem comes with standard alert messages for every monitor.
With help of the e-mail template monitor you can customize the message text for every single monitor. You can use many keywords which are going to be replaced when an
alert is going to be sent. I.e. the keyword %IP% is going to be replaced by your current IP address. A complete list of all available keywords can be found in the CheckSystem info file.
