After determining which events should be raised for your monitoring environment, you need to establish a comprehensive notification infrastructure for your enterprise by configuring Enterprise Manager to send out email and or pages, setting up email addresses for administrators and tagging them as email/paging. In addition, depending on the needs of your organization, notification setup may involve configuring advanced notification methods such as OS scripts, PL/SQL procedures, SNMP traps, Webhooks or Slack. For detailed information and setup instructions for Enterprise Manager notifications, see Using Notifications.
