The Granular Event Management framework provides customized event, including email alerting on the status of specific VPN tunnels, alerting based on schedules (such as 8am to 5pm, or 24 hours a day), and alerting to specific email destinations based on severity and functionality handling. You can also configure GEM to send an alert when changes are made to a managed appliance by a local administrator through the appliance management interface rather than through GMS. This is a predefined alert available on the Policies panel. For a list of the predefined alerts, see Using Granular Event Management .
