As we saw in the earlier sections, Enterprise Manager collects monitoring and configuration information round-the-clock, and schedules the job at a specified time. All of these activities continue to happen even when nobody is actively looking at Enterprise Manager. Whenever required, System Administrators can see the history of metric alert, policy violation or job results. But there are some alerts, policy violations, or job results that need immediate attention. Enterprise Manager provides notification framework, and by using this, notifications for alerts, policy violations, and job failures can be sent out.
Major building blocks of Notification system are:
Notification Methods
Enterprise Manager provides support for various notification methods that include SNMP trap, emails, and so on. Enterprise Manager console provides an interface for configuring the notification methods. For example, console provides an interface to configure SNMP notifications, where the user can provide details like SNMP community, SNMP host, SNMP port, and so on.
Notification Rules
System Administrator should get paged only for the critical resources and only for the critical performance indicators or policy violations. Enterprise Manager provides support for Notification rules AND using that, Administrators can define for what type of events a notification should be sent out and which notification method should be used.
