Alerts: Alert Recipients, Alert Classifications, and Severities
Alerts are email messages or notifications containing information about a specific function (or alert
classification) or functions such as a hardware or anti-virus problem, sent to an alert recipient. An alert
recipient is simply an email address to which the alert notifications are sent. The information contained
in the notification is determined by an alert classification and a severity. You can specify which alert
classifications, at which severity, are sent to any alert recipient. The alerting engine allows for granular
control over which alerts are sent to which alert recipients. For example, you can configure the system
to send only specific alerts to an alert recipient, configuring an alert recipient to receive notifications
only when Critical (severity) information about the System (alert type) is sent. You can also configure
general settings (see
