How to create Notification Rules in OEM 10g

Overview:

Oracle Enterprise Manager (OEM) 10g can send the Email Notifications to administrators when an alert is occurred. Alerts are notifications when particular metrics thresholds are crossed. For example, when a tablespace becomes 97 percent full this can be considered undesirable and have Oracle to generate a critical alert.

Notification Rules are defined sets of alerts on metrics. Metrics are automatically applied to a target when it is discovered by Enterprise Manager.

Enterprise Manager provides a series of default rules. We can modify these default rules or we can create the new rules to monitor only specific metrics for specific targets.

Here I am going to explain “How to create a Notification rule in OEM 10g”.
